animals


In my blog of October 11, 2018, I shared images and some information on various flora that are found on Bermuda and promised to talk about some of the species that have become invasive. You may wonder why invasive species on Bermuda might be relevant to us in Connecticut. Islands as small as Bermuda or as large as Australia may have species that are unique to their location and that have fewer defenses against introduced plants, animals, fungi, or microorganisms. These places are great concentrated studies in the effects of introduced species.

We have seen many invasive species become hot topics as they moved from other parts of North America or even other places on the planet into non-native locations in the Northeast. The Connecticut Invasive Plant Working Group lists over 80 plants that are currently problems, some of which moved into our region in just the course of a decade. Transported wood that is infested with the Emerald ash borer or the Asian longhorned beetle has enabled these insects to move easily from state to state.

The isolated volcanic islands of Bermuda were not subject to invasive species for most of its history. There were only 165 species of vascular plants, 5 species of bats, a species of skink and another of turtle on the islands when Bermuda was discovered. Over the next several hundred years thousands of plant and animal species were brought by ships to the islands, sometimes intentionally but more often not. Some came as stowaways as seeds in hay or soils, on ocean currents, as insects in food stores, or in the bilge water of the ships themselves.

Until Bermuda was visited by the first Europeans in 1505 there had been no human-related importing of flora or fauna to the archipelago so it is a great microcosm of the effects of species introduction. When settlers come to a new place the first thing that they attempt is to make it ‘home-like’. The introduction of rabbits to Australia in 1788 by British penal colonies. Within ten years they numbered in the millions and ate enough vegetation to cause widespread erosion issues.

One of the first species introduced to Bermuda were the pigs that were released on Bermuda in the late 16th century. By the time a European settlement was established in the early 17th century the pigs had become abundant and feral. You may wonder why pigs were released in the first place. It was because the islands were used a place to replenish food and water, kind of a 17th century truck stop by ships. The pigs did untold damage to seabird and turtle breeding colonies.

Cockroaches, Periplaneta americana, came to Bermuda as egg cases in the bilges of a ship in 1621. Wireweed, Sida carpinifolia, was already a rampant invasive in 1669 when then-governor John Heydon was calling for tenants to pull it up by hand.

Many of the introduced species were brought in to control other species. The Jamaican anole, Anolis grahami, arrived in 1905 to control the Mediterranean fruit fly, Ceratitis capitata, and has since become naturalized. A beneficial introduction came in the form of honey bees, Apis mellifera. A beekeeping record dated May 25, 1617 stated that “The bees that you sent doe prosper very well.”. The Bermuda palmetto (Sabal bermudana), a native plant, is one of the main nectar sources for these bees. The giant Cane toad, Bufo marinus, an introduced species, was brought in to control garden pests but unfortunately consumes a lot of bees.

The Indian laurel, Ficus microcarpus, an ornamental garden tree was not considered an invasive species until the 1980s when a pollinating wasp was introduced to the island. Known as a strangler fig like its cousin the banyan, Ficus benghalensis, the Indian laurel can crack through walls and water tanks. It is a primary food source for the starling, an introduced species that does a lot of damage as they spread invasive seeds from the Brazilian pepper, Schinus terebinthifolia, the asparagus fern, Asparagus densiflorus, and the Indian laurel.

Casuarina, Casaurina equisetifolia, over-shades native plant species and causes soil erosion. It was introduced from Australia in the 1940s as a windbreak but no plants grow beneath it. Kudzu, Pueraria montana, is familiar to Connecticut gardeners as it is also on the Connecticut Invasive Plant Working Group list.

With 23 of the top 100 invasive species in the world, Bermuda is still at risk of additional invasive species as most of their food and consumer goods are brought in by ship. Visitors or traveling Bermudians also bring plants, fruits, and seeds on to the islands. When you travel anywhere in the world and see warnings about bringing back fruits and plants or prohibitions against moving wood, visiting farms, or petting livestock it is for the good of all to heed that advice.

snow and tree

As I sit here inside, watching the cold wind blow and snow pile up outside the warmth and safety of my little writing spot, I wonder just how all those living beings outside are surviving. Trees are swaying in the wind, and birds trying to visit the feeder are forced to alter flight plans while sporting ruffled feathers. The only animals I see are hunkered down squirrels. And just where did the insects go?

A little research tells me all of the annual plants are dead. They completed their life cycle in one year going from germinating a seed to producing seeds which are waiting winter out to make new plants in the spring. In my vegetable garden I call them volunteers. You know those tomato seeds that germinate from last year’s rotted tomato fruit that dropped to the ground and its seed volunteered to grow where I didn’t put this year’s crop. The seed survived through the winter, not the plant. Annual weeds drop seed in this manner, too.

IMG_0877default

Perennial plants are a different story, although their seeds can do the same overwintering as annuals, the existing plant can live through the winter to grow another year, hopefully for many years more. Trees and shrubs are woody perennials that have woody above ground structures and roots that overwinter. Herbaceous perennials overwinter their roots and crowns only. The above ground portion of the plant dies back, but the crown and roots are alive at level or below ground. Perennial plants go dormant, living off of stored food until warmer weather returns. Storage organs of plants are the thick roots, rhizomes and bulbs. Just how they prepare themselves to make it through the winter happens at the cellular level long before freezing temperatures begin.

Plants are triggered by the amount of light and the amount of dark they experience, and lower night temperatures signal to get ready for winter rest and dormancy. Different species have varying light and temperature levels signals. Deciduous trees and shrubs must begin the process of losing their leaves by first stopping the production of their food. We notice it in slower growth and in the leaf color. The leaves are the food factory of the plant where photosynthesis happens. Carbohydrates are made then stored in roots and woody parts of the tree or shrub. Lots of light and water results in good growth and food storage, but when light amount lessens, leaves slow down production. Chlorophyll is also produced during photosynthesis, giving the leaf a green color. Once the leaves stop working, no more chlorophyll is produced and the other plant pigments of red and yellow are exposed now that there is no green chlorophyll to cover them. This is when we see beautiful fall foliage. The next change happens in a specialized layer of cells at the point where the leaf stem (petiole), attaches to the twig called the abscission layer. These cells enlarge and harden to choke off water flow to the leaves and the leaf slowly dies and falls off.

tree in fall

The next cellular change is called cold hardening. It happens within the vascular system containing the plant juices and water. If water inside the cells freeze, it will rupture the cells, permanently damaging the plant. The cold hardening process increases the sugar content of the water, and makes other protective chemicals, lowering the freezing level of the plant liquid. Basically the plant makes its own antifreeze. Cell walls are also changed to allow water leakage into spaces just outside the cell so if crystals do form, damage will be avoided. The acclimation of all these changes makes the plant able to tolerate below freezing temperatures. Fall pruning or fertilizing with nitrogen during August and September stimulates new growth interrupting the cold hardening process.

Evergreen trees and shrubs have thick leaves with waxy coatings to prevent moisture loss. Some broadleaved evergreens have gas exchange openings called stomata on the underside of the leaf. In very cold weather the leaves will curl as the stomata close to prevent moisture loss. Rhododendrons are a good example. Evergreen plants will continue to photosynthesize as long as there is moisture available, but much more slowly during the winter.

Animals and insect have the ability to move, unlike plants. They can migrate, hibernate or adapt to winter’s cold. Certain birds migrate to warmer areas and better food sources. Hummingbirds, osprey, wood ducks and song birds fly south, and some birds from far north in Canada come south to spend the winter here. Juncos, snowy owls and bald eagles summer at a higher latitude and spend the winter nearer to us. They go where they can find food.

Some animals go into a winter dormancy or hibernation. This phase consists of greatly reduced activity, sleep or rest, and lower body temperatures while their bodies are sustained from stored fat. Bears, woodchucks, skunks, bats, snakes and turtles all have true hibernation, not waking until light levels increase and food sources begin to be available again. Bears and bats find caves, woodchucks, and skunks dig tunnels, snakes and some turtles burrow into soil and leaf litter, all in protected sites.

Other animals such as chipmunks have underground burrows lined with stored nuts and other food. Beavers do the same in lodges they build just above water, and line with stored logs to feed on during the winter. They sleep for long periods, only waking to eat and if maybe take a short walk above ground before returning to their den. Fur bearing animals will grow a thicker winter coat to help keep them warm, and may be a whiter color to provide camouflage in the snow.

Voles are active all through the year. In winter, they will tunnel through the snow, just on top of the ground looking for plants material to eat. They will strip the bark off of young trees and eat the roots. Voles store seeds and other plant matter in underground chambers. Mice are active and breed year round, living in any protected nook or cranny they can find, including our homes. They store food in hidden spots away from human and predator activity. Check for mice tracks around your foundation after a freshly fallen snow to see if mice are using your house for their winter quarters. Moles are active deep underground, below the frost line, in an elaborate array of tunnels. They feed on soil dwelling insects throughout the winter. I guess you could say they go ‘south’ in the soil profile during cold weather of winter.

Squirrels do not migrate nor hibernate, they adapt. They are active all winter, raiding bird feeders, and feeding on stored nuts. They grow a thicker coat of fur and fat for winter. Squirrels make great nests high in trees, well insulted with leaves. Several grey squirrels will share a nest to keep warm. They are often too quick to get a close up photo!

Insects as a group are very large and diverse. Some migrate in their adult stage such as monarch butterflies and some species of dragonflies. Others overwinter in pupal stages like the chrysalis’ of spice bush swallowtails or cocoons of Cecropia moths.  Others adult and immature insects, depending on species, enter a state of diapause, similar to hibernation in animals, to overwinter during the winter. Diapause is a dormant semi-frozen state for some insects.  And like plants, changes at the cellular level occur, too. These insects produce an alcohol-like chemical and added sugars to the moisture in their bodies to prevent freezing, just like vodka will not freeze when placed in our home freezers. Insects will first seek out a protected place in the soil, leaf litter or under lose tree bark or rotten logs.

The brown and orange woolly bear caterpillar burrows into the forest floor to spend the winter as in its larval stage. In spring it will come out of its dormancy to pupate, later becoming an Isabella tiger moth.

Other insects lay eggs singly or in mass groupings, which are equipped to live through the winter and hatch when conditions are good again. Gypsy moths spend the winter as egg masses, tolerating down to -20 F temperatures. Crickets are another insect group which lays eggs in the fall on the ground that will provide a new generation of night songs for us to enjoy the next summer.

“Feeling a little blue in January is normal”

  • Marilu Henner

The one thing I like about January is that at least the days are getting a teeny bit longer. We still have the cold weather and probably a bunch of snows will fall, but the nights are shorter and I am fooled into thinking spring will soon be here. While I like to escape into the wilds in the warmer, more colorful months, it can be a more difficult enterprise now. Snows may not allow an easy walk in the woods, but the roads are clear, and they will have to do as a means of checking out the January happenings outdoors.

Although cold, the air is nice and clean (it seems!) and crisp, providing a refreshing change to an extended existence in an indoor environment. And there is still much to see in the winter. Bird species may not be as abundant, but the ones that are still here provide a nicer experience for me than watching fish in a tank would.

Pileated woodpeckers may be elusive, but they are quite vocal, and so they often give away their location as they gad about in the woods. Water birds are still around- a kingfisher is still finding stuff to eat in areas of open water- and mallards and Canada geese are, too. Coots may be seen in open water near the shore, and merganzers and ruddy ducks can be found in small or large flocks in the coastal areas. And Cooper’s hawks, as well as sharp-shinned hawks, small accipiters that prey on birds, can be seen buzzing bird feeders for easy pickings on a winter’s day.

In my town, there is a large population of black vultures now, which is a remarkable development as just a few years ago avid birders would ‘flock’ to an area where a black vultures was reported to be. During the 1990’s, black vultures were considered very rare visitors to Connecticut, but in the last few years, they are definitely staying year- round and breeding here. You can tell black vultures from turkey vultures in flight by the white bands on wing tips, versus the half silver wing undersides of the turkey vultures.  Up close, the gray faces of black vultures are readily distinguishable from the bald, red faces of turkey vultures. Black vultures will often congregate on chimneys on cold days.

We had very cold weather the last two weeks- down in single digits on a few mornings and not much above the teens the rest of the time. Today, it is raining and fifty two degrees. If warm conditions keep up for a few days, fireflies may come out from their winter hiding spots in bark crevices, Look for them on sunny sides of trees in wooded areas. They will not fly, too logy for that, and will return to their resting places as the weather gets cold again.

When we have snow cover, that presents an opportunity to check out animal tracks in the snow. Deer tracks require no great hunter-like skills to figure out, but others may be tricky. I get a kick out of mouse tracks- don’t’ know why- maybe because they are one of the few animals that leave a tail print between the footprints.

Two of my favorite native plants that give interest to the monotone winter landscape are the redosier dogwood, Cornus sericea and winterberry, Ilex veticillata. Both plants offer a splash or red to a snowy landscape, and winterberries offer a food source for many birds and some small animals. Winterberry is found in the wild along edges of woods and swamps, and redosier also prefers similar areas in the wild.

Even though it is not a native plant, I do love the Norway spruces when they have established mature stands. Red squirrels, at least, also appreciate the seeds that are one of their important food sources in the winter. You may come across piles of the spruce cone scales where the little pissant red squirrels take off the scales to access the seeds inside.

Indoors, though, it is warm, as well- lit as you may desire, and a better relaxing environment in January. Until the warm weather comes, perhaps an orchid in flower may providing a charming blush of living color, while we wait for nature to do the same.

Sometimes, in the course of our lifetime, we may find ourselves in the right place at the right time to make a difference in the life of some living thing. Maybe it is just the simple act of putting a nestling bird back in the nest from which it has fallen. Or we may be able to transplant a native plant to a safe location just a few feet away from the reach of a roadside sickle bar. Once I had to scoop up with a towel a baby fox that had fallen asleep in a dangerous place on the golf course and put it back with its brothers (or sisters!) who had chosen their resting place wisely. While it may not always be a good thing to interfere, sometimes it may be the best thing.

Where I work, we often have a surprise when mowing early in the morning. This year when I was mowing a green with lights on just before sun-up, I noticed something that I thought was an earthworm moving in the path of the mower. At the last second before running it over, the creature starting running on little legs and I stopped in the nick of time. It was a tiny salamander. I put it in a plastic cup with a lid I always have with me and later on I put the little guy in the woods near a vernal pool.

In a similar way, the eft form of red-spotted newts often end up on greens or fairways the day after a rain. Being so small, they are often unable to make it back to the woods where they belong. So placement in a plastic cup keeps it safe until the opportunity comes to set the little eft on the forest floor. Like Shakespeare wrote- ‘all’s well that ends well’.

Our giant silkworm moth caterpillars have a high percentage that are killed by introduced parasites meant to control the gypsy moth caterpillars. When I find young silkworm moth caterpillars in the wild, I like to raise them so prevent parasitism. When they form cocoons, I take them back from whence they came. Cocoons can be attached to twigs of the host plant with a bread tie or put in leaf litter below.

Turtles often are the recipients of human kindness, especially when they attempt to cross roads. Box turtles are frequently seen crossing roads the day after a summer rain, and many have been helped across by kind people. Some turtles travel great distances to lay their eggs and encounter similar hazards. Once we found three spotted turtle eggs while renovating a bunker. Carefully marking them to keep them right-side up, they were transferred to an aquarium and placed under sand. Within two months they hatched and were released on the banks of the pond where the eggs where originally laid. If it were possible for turtles to leap for joy, they would have.

If a baby bird is found on the ground, it is important to note whether it is a nestling, which has fallen from the nest prematurely, or a fledgling, which should be out of the nest. The cedar waxwing shown below was a fledgling found on the ground on a cart path. It was moved out of harm’s way to a low branch nearby where the parents easily found it. Unlike many other animals, parents will still feed and care for baby birds even after human handling.

There are walking sticks I find every year on certain plants on a particular power line right- of- way. A lot of tree and shrubs were marked to be cut down to clear the lines including a small clump of filbert and viburnum that are the host plants for these insects. I wanted to try to save a few before the chain saws arrived, so I took my beating sheet and was able to find several tiny walking sticks that probably had hatched that week. They were raised that summer until work along the lines was complete. Since the host plants were left standing, the walking sticks were returned.

This year we had an interesting incident involving honey bees. Since it was late in the year and many flowers were no longer available, honey bees were very busy on black and blue salvia in a large planter outside the clubhouse. The problem was, someone had fallen into and smashed the salvia and it had to be removed. Our gardener noticed that over fifty honey bees were still swarming around where the plant had been, and they were even trying to get nectar from the petals remaining on the ground. Since a planting nearby along a stone wall also had the same salvia, we took small branches with the flowers and held them over the ground where the bees were. The bees immediately went for the flowers on the stalks and stayed there, or flew with them to the front planting. We shook the bees off, and they found the new flowers right away. We were able to get all the bees over there in this way. They probably would have found the other salvia on their own, but it was something to do…

To help wildlife on your own property, include water dishes for toads, chipmunks, and other animals, birdbaths and perhaps bird and bee houses. Provide shelter for  birds such as small trees and shrubs, which may also double as food sources and nesting places.

When you are out and about enjoying  nature in the wild or in your own back yard, it is always satisfying and cheering to one’s own little self to see something else become better off because of what we may be able to do. Just think- you don’t have to be a nature expert to become, at least for a little while, a bee whisperer.

Last week’s Ladybug Blog extolled the historical, cultural, and culinary delights of pumpkin. It seems as though you can’t step foot into a grocery store, candle shop, or cafe without being inundated with products that revolve around pumpkin spice. As ubiquitous as the combination of cinnamon, clove, and allspice have been the past few years I remember a time when the flavor of early fall was apple; from cider and cider doughnuts to pies and apple butter.

Many a school field trip or family outing revolved around a trip to an orchard to pick one of the many varieties of apples available in New England and return home laden with bags of this versatile fruit. The pleasure of these adventures was increased if the destination also had a working cider press. That sweet/sour smell of the overripe apples being pressed says fall much in the same way that a freshly-cut fir tree hints that Christmas is on its way.

Apple orchards have been a part of Connecticut and New England since cultivated apples (Malus pumila also known as M. domestica) were brought here by the European settlers in the 17th century. The first recorded apple orchard was planted in 1625 by the Reverend William Blaxton in what is now Cumberland, Rhode Island. Reverend Buxton cultivated the Yellow Sweeting apple which later became known as the Rhode Island Greening, a cooking apple that has a greenish-yellow flesh. Before that only the small, sour, wild apples which we know as crabapples grew in North America. Crabapples are used as ornamental trees in landscapes and as they are heavy bloomers are great sources of pollen for cross-pollination in apple orchards, are a good source of pectin, and as a rootstock that provides cold-hardiness to domestic apples.

The use of crabapple or other apple varieties as a rootstock in grafting is very important in modern orchard farming. Apple trees grown from seed do not grow true to their parent plant and can be anywhere from 12 to 36’ tall, features that are not conducive to consistent apple production and ease of harvest. Therefore, grafting, the technique that combines the beneficial traits of 2 or 3 apple varieties is greatly beneficial. In the simplest of terms, grafting is the procedure by which a scion (a piece of last year’s growth that has 2-3 buds) is cut from an existing tree of the desired apple variety.

The scion is inserted into the cambium (vascular) layer of the understock (rootstock) of another apple variety that may bring traits such as disease resistance, crotch strength, adaptability to heavier soil, a slow growth rate, adaptability to espalier training, or the above-mentioned cold-hardiness. The new graft is generally bound with tape and a grafting compound. Detailed information on grafting can be found in books or online.

Cider apples are usually a combination of cultivars that are grown specifically for use in cider production to have higher sugar and tannin levels and are often more astringent than the eating and baking varieties. These qualities contribute to a final product that has a deeper flavor. Among cider apple varieties are some that are higher in sugar which causes their cider product to ferment resulting in hard cider. In fact, hard cider was an important beverage at a time when refrigeration was unavailable. Most apple cider produced today is pasteurized, a process that heats the unfiltered apple juice to prevent bacterial contamination. It also destroys any yeast that would cause the juice to ferment creating a more stable non-alcoholic product. In fact, ‘Johnny Appleseed’, the folklore hero born as John Chapman in 1774, planted seeds that produced apples that were only good for hard cider (or applejack), not for eating.

In 1993 The Enfield Historical Society brought a manual cider press to the Old Town Hall Museum. Since we were members of the Society my husband Russ and some friends were enlisted to turn the press.

It was a beautiful, sunny fall day, perfect for an outdoor exhibition. Our children and friends were among the crowd that gathered to watch the action. The resultant cider was not distributed as it had not been pasteurized but there were jugs of pre-pressed cider for the enjoyment of all.

Crates of apples await their turn in the press.

Humans are not the only members of the animal kingdom that appreciate ripening apples. At this time of year, it is almost impossible to get near an apple tree without being in the presence of yellowjacket wasps as they forage for the sugars that are important to their developing queen in late summer. As overly ripe apples fall to the ground the yellowjackets will swarm the fallen fruit.

 

A beautiful Mutsu apple showed the scars of an encounter with yet another species that wanted to feed on the delicious ripening fruit. Although this apple was about 5 feet above the ground an animal, possibly a raccoon, had attempted unsuccessfully to get it.

We, however, picked many Mutsu (also known as Crispin) apples, a very crunchy and sweet variety that is a cross between the Golden Delicious and the Indo cultivars that is great for eating and several pounds of Cortland destined for pies, crisps, and apple butter. Connecticut’s orchards are still going strong so visit the Connecticut Apples site to find one near you and enjoy some of the many delicious varieties that are grown in our state.

There is a deciduous plant that grows as a small tree or shrub, is native not only to the Northeast but to most of the temperate Northern Hemisphere, is a popular ornamental species appreciated for its flowers and its fall color, and it produces a deep purple fruit that is both edible and delicious. George Washington had specimens of this plant on his Mount Vernon estate but even before that the Native Americans mixed the fruit with dried meats and fat to create pemmican, a food that is high in both energy and nutrition. This plant goes by many names, some of the more unusual ones are sarvis, saskatoon, and chuckley pear. Have you guessed what it is yet? Here are some of the more common monikers: wild plum, sugar plum, service tree, and shadblow. Have it yet? Let’s keep going. How about shadbush, serviceberry, or Juneberry? Now you know it, it’s Amelanchier.

IMG_20170907_122432960_HDR

Serviceberries

In fact, there are so many bits of lore surrounding the etymology of all of the various names attributed to this plant. Is it called sarvis or serviceberry because the fruit is similar to the European Sorbus or because its bloom in the spring coincided with the time that Appalachian mountain roads became passable enough for traveling clergy to hold services? Or is it shadbush or shadblow because the flowers appear when the shad are running? Or Juneberry because, you guessed it, the fruit appeared in June? I think that my favorite name is saskatoon which is derived from the Cree name for Amelanchier, misâskwatômina, which also lends its name to Saskatoon, Saskatchewan where the plant is native.

One of the most common species of this plant that is found in New England is the Amelanchier canadensis, known as the Eastern shadbush. It comes as no surprise that this plant has so many names as there are between 6 and 33 species (depending on the source) due to the wide variety of hybrids and the fact that it is also found in Asia (A. sinica or Chinese serviceberry) and Europe (where the species A. ovalis is known as Snowy mesiplus).

Adding to the confusion is that fact that this plant can be a small tree or a multi-stemmed clumping shrub. This happens when the new growth is heavily browsed by deer and rabbits and the plant takes on a tree-like shape instead of a shrub similar to many of the its fellow members of the Rose family. In full sun or part shade it can reach 20’ tall and has an airy, open look to it that is compounded by the fact that the white flowers emerge before the leaves in the spring. If it is left to its own devices then the suckers that are produced from the base of the plant can grow into a thicket.

The fruit that succeeds the flowers starts as a yellow, single-stone, berry-like ½” pome that hang in terminal clusters of 1 to 4 fruit. As the season progresses and the fruits ripen their color shifts to red, purple, and finally the deep almost black purple that signifies maturity. We have received several calls from the Connecticut Poison Control Center requesting identification of the Serviceberry fruit as it appears to be as attractive to children as it does to birds and wildlife. It is always nice to be able to report that it is in fact edible and harmless. When fully ripe the taste is sweet and a bit tart at the same time. I had a bowl of them in the fridge and my husband ate one, expecting that it was a grape, and was a bit surprised.

IMG_20170914_190452695

The plum-like interior of the fruit

Amelanchier is not only grown for its fruit but as a popular ornamental shrub/tree. Although they are not drought tolerant and require good drainage and air circulation they do provide interest throughout the year. The delicate 2” white or pink blossoms appear in the spring around the time that the shad are running in the Connecticut River according to folk lore, generally in early April. The leaves follow the blooms and then the berries which are ripening now. Soon the leaves will turn from green to yellow to a beautiful orange or red and when they fall the tree will still provide interest in the form of its unusual grey bark which shows fissures as it ages.

The interesting bark of Amelanchier

In addition to the aforementioned deer and rabbits Lepidoptera caterpillars and other insects also feed on Amelanchier. Among these are spider mites, sawflies, flatheaded borers, bark beetles and aphids. I did not see any aphids when I took these images but I did see a specimen that was heavily populated with Asian lady beetles, a heavy predator of aphids, in three different stages of development.

Amelanchier are susceptible to several diseases including Fire blight, Leaf spot, and Gymnosporangium rust, which affects the leaves, twigs, and fruit with distinctive orange lesions and spores. The alternate hosts of Gymnosporangium are juniper and cedar.

Another common affliction of stone fruit that also infects Amelanchier berries is Brown rot. Brown rot, or Monilinia amelanchieris, fungi persist in blighted blossoms, twig cankers, or on mummified fruit. In the cold winters of Connecticut it only survives by overwintering on fallen infected fruits. Apothecia are produced on berries that overwintered on the ground. These small mushroom-like structures release ascospores which can infect blossoms and cankers but not the fruit. In more temperate areas when early spring temperatures combine with moisture the conidia, the asexual reproductive spores, will be produced on cankers or mummified fruit that remained on the tree. The conidia of Monilinia form linked chains on the blighted tissue of blossoms or twigs from which the mature spores will detach to be spread by air, splashing water, or insects.

When vectored by feeding insects these spores will entire fruit through the open wounds. In the moist, moderately temperatured climate of the developing fruit the conidia will germinate in 2-4 hours although it may remain latent in green fruit. Mycelium, the vegetative part of the fungus that absorbs nutrients, and conidia, the spores, will sprout from the infected fruit causing the fruit to decay and turn brown.

When vectored by feeding insects these spores will enter fruit through the open wounds. In the moist, moderately temperatured climate inside the developing fruit the conidia will germinate in 2-4 hours although it may remain latent in green fruit. Mycelium, the vegetative part of the fungus that absorbs nutrients, and conidia, the spores, will sprout from the infected fruit as small, circular brown spots that cause the fruit to decay and turn brown. Within these areas tufts of greyish spores appear as the fruit mummifies. The fruit may remain on the tree or drop to the ground until the spring when the cycle starts again. Cleaning up dropped fruit and debris will help to cut down on reinfection and it is suggested that Amelanchier be planted in areas where the messy dropped ripe fruit is not an issue.

Better uses for the ripened fruit include jams, pies, wines, ciders, or dried like cranberries for use in cereals, trail mix, and snack foods. Or you could whip up big batch of that Native American favorite, pemmican, if you happened to have a load of thin slices of bison meat that have been dried in the sun and pounded into a powder, mixed with melted fat and the dried serviceberries and formed into patties. Just in time to store it away to delight your family at Thanksgiving!

“ The world’s favorite season is the spring. All things seem possible in May.”

May is usually the time of warmer weather and sunny days that brighten the landscape again with flushes of green leaves and splashes of color from flowers. We look forward to another season of gardening and other outdoor activities, and the encounters with nature that are unavoidable as one ventures outside.

This May has been colder than I would prefer, but at least it has seen more rainfall than last spring. The reason this is especially good news is that the gypsy moth caterpillars have recently hatched, and the rains bring hope that the fungal pathogen, Entomophaga maimaiga, will help diminish populations of this pest. Last year they went unchecked for most of their caterpillar stage as drought conditions kept fungal spores from germinating.

Ferns are opening up now and their graceful forms are a welcome decoration wherever they appear. My personal favorites are the scented fern, cinnamon fern and the diminutive polypody which are often found growing together on rocks with mosses. Polypody work well in dish gardens coupled with moss and partridgeberry, and can be brought indoors for the winter, or left outside if that works better.

Most trees have leafed out by now, with the pokey sycamores and hickories lagging behind, as usual. With the flush of leaves come the migrating warblers. Caterpillars are now found eating leaves in the tree canopies, and this is where many of the warblers find some protein for their return to northern breeding grounds. Rose-breasted grosbeaks, scarlet tanagers, orioles, and thrushes are all back and they have transformed the woodlands to a symphony of birdsong. Also, barred and great horned owls born in late winter and early spring have left their nests, and parents can often be heard calling to their young. Many robins have already hatched their first brood as of two weeks ago, so it must be true that the early bird gets the worm…

Dogwoods have had spectacular blooms this year, and crabapples and viburnums as well. Yellow water lilies, Nuphar lutea, are beginning to bloom. This plant closes its flower late in the day, trapping beetles or flies overnight who will pollinate it as they try to escape.

Limber honeysuckle, Lonicera dioica, a native vine-like shrub that is infrequently encountered, is also starting to bloom. The tubular red flowers have distinctive yellow stamens and attract hummingbirds and native bumblebees. Fringed polygala, a small, pink native wildflower with flowers that make me think of Mickey Mouse with an airplane propeller, are just beginning to bloom and are often found together with stands of the native Canada Mayflower. Native columbine are also blooming now and native Pinxter azalea should be following shortly.

Interesting galls are forming on the young leaves on wild cherry. Spindle galls, caused by the mite Eriophyes emarginatae, are red spindle-like structures of leaf materialcaused by the mites feeding within. These tiny mites begin feeding as soon as cherry leaves expand in the spring. Although they can occur in large numbers, the galls will not stop leaves from photosynthesizing, and the trees will put out new leaves after mites are inactive.

Giant silkworm moths such as Cecropia, Polyphemus and Luna have been overwintering in cocoons and should be eclosing any time from mid- May to June. These spectacular moths usually fly during the night, but are often attracted to lights. Since they cannot feed, if you find any lingering about in the daytime, don’t worry about what to feed them- just enjoy their company!

Swallowtail, Painted Lady, American coppers, Juvenal’s duskywing and many other butterflies are out and about. Wherever you see them, check out larval host plants for caterpillars. Sometimes they are as close as your own backyard.

Here’s hoping for timely rains during the summer, warmer days to get our blood moving and an abundance of fruits, flowers and birds that to follow May’s fore-running to summer.
