Not so wild Irish rose.

Vacations are for traveling and relaxing, seeing new lands and experiencing cultures other than our own. I did just that this summer on a trip to Ireland visiting the entire coastal perimeter of the country. I am a plant person at heart, so of course I was enamored with the plant life I saw, touched, and even ate and drank. The golden barley in the fields was to become an important ingredient in the Irish Guinness beer brewed in Dublin. We took a tour of the brewery to learn how the fruit of the hops plant and the grain of the barley are turned into the well-loved stout beer.

Along the coastal route we traveled, we did not see many vegetable farms as they were located more inland where there were better growing conditions and soil. We did see many fields with sheep and cows. Beef and dairy cows were often feeding in fields not used for hay.

Often large fields would have a lone, ancient tree standing within its boundaries, and could be any species that happened to take root on the spot. Our tour guide told us those trees are known as fairy trees which house the fairies of Ireland. Fairies in Ireland are not nice and cutesy like we Americans think of them. In Ireland fairies are tricky beings, and can bring havoc and bad will to those who disturb them. For this reason, farmers will leave a large tree in the middle of his field, even driving around it when seeding and growing crops, avoiding tilling up the area so as not to disturb or offend the fairies residing under it. The superstitions are handed down with the generations, and many stories of them may be found in bookstores on the local legends.

We passed peat bogs which are wetlands covered in accumulated dead plant material and mosses. Peat takes centuries to form under the acidic and anaerobic conditions. Layers of peat were traditionally cut out of the bog, left to dry and then used a fuel source to burn inside fireplaces to heat homes. Now a day, modern heating is used in Ireland, and bog management laws limits on the amount of peat harvested. Peat moss used in gardens is also harvested from bogs. Since it takes centuries to form, it is not really a very good renewable resource.

 

In windswept, boggy meadows along the seaside were plants that looked like cotton blowing in the wind. It is called bog cotton, Eriophorum angustifolium, a grass-like sedge plant with fluffy seed heads. Each seed is attached to a fluff of hairs/bristles that can catch the wind to be carried far away. Great method of seed dispersal created over eons to ensure the survival of the species.

Heather grew wild among the rocky areas and tolerated the harsh, windy climate well. It was low growing among the native grasses providing a subtle lavender color to the fields.

Foxglove is a native weed just about everywhere in Ireland. Its purple nodding bells arising from waste areas and rock walls. Called Fairy Thimbles in folklore, they are deemed unlucky if you bring them into the house in case you let a naughty fairy into the home. Foxgloves are biennial, with second year plants blooming from June through August.

While in Northern Ireland at Malin Head, I came across the most unusual hedge plant planted in multiple yards and outside several establishments. After asking a local or two, its identity was revealed as Hebe, a broad leaved evergreen plant with showy purple flowers in July and August. It is native to New Zealand and the folks I spoke with weren’t sure how it originally came to their town, but they share it readily with neighbors. Hebe is hardy there, but will not take temperatures below freezing. Even one exposure to a freeze and its top growth will die back. The stands of I saw were happily six feet tall and tolerating even this northern most town on the coast.

What would a visit to Ireland be without the mention of potatoes? Several museums and tour guides told the history of the Irish potato famine caused by the fungal disease of late blight, Phytophthora infestans, the same disease that infects tomatoes and can wipe out a crop. The English withheld all other food sources from the Catholic following Irish people unless they denounced their religion. Once the potato blight hit for several years, there was no food left resulting in mass deaths and migrations to other countries. Still today, the entire population of Ireland has not reached the numbers it had before the blight hit.

At the end of our trip, we packed up our mementos of Irish lace and tweed caps along with the rich stories of Ireland. My memory cards are full, both the physical one in my camera, and the one in my head.

By all these lovely tokens September days are here, with summer’s best of weather and autumn’s  best of cheer”

September is here with its splashes of goldenrods, Joe-pye and other late summer flower. Butterflies that migrate are having their last hurrah and late season caterpillars are ready to pupate. Fruit trees are loaded down with apples, and the air in the early morning may be scented by ripe wild grapes. This is a great time of year, still green, but showing signs of the autumn that will soon arrive.  Getting outside now has its own sets of rewards.

While moving rocks in a landscape, one had a small mud like structure stuck to the underside. This was the work of the female Eumenes fraternus potter wasps construct mud brood  that look like miniature jugs. After an egg is laid inside with a good supply of caterpillars or beetle larvae to feed the larva when it hatches, the female seals the hole. Since the female potter wasps do not defend their nest, you can check inside to see the food stores/larva or pupa.

Wildflowers in bloom now include cardinal flower, turtlehead and closed gentians, all of which can be found in damp soils, especially along banks of ponds and streams. They can be found under shrubs or among other plants growing in wet areas. Cardinal flowers are a good plant to stake out for the hummingbirds that love their nectar. Bumblebees can be seen squeezing their way into to the gentian and turtlehead flowers that most other bees do not have the muscle to get inside.

There are spectacular late season caterpillars, like sphinx and tussocks. Also the aptly named asteroid, which feeds on both aster and goldenrod flowers and flower buds.

I had to rescue an eft of the red spotted newt the other day. They sometimes come out of the woods after rainy days in warm weather, and this little fellow had come a few hundred yards away from the nearest wood line and was in the middle of a fairway being mowed. Disaster was averted, and the eft was brought to a wooded area near a vernal pool.

I returned to an area of woods off a hiking trail that has a number of nodding trillium, Trillium cernuum.  They now have the brilliant red berry that contains seeds, but you have to lift up the large leaves in order to them. This is one of my favorite trilliums, mostly because it is hard to find, and then the flowers are a reward for those who peek under the leaves to find them.

This summer has been warm and droughty after a fairly wet May and June, and even part of July. There has been flooding after the numerous rains where soils are heavy and do not drain well. Then days in the 90’s coupled with poor surface drainage caused turf grasses to die. Even grasses in a light soil may have had shallow roots going into the hot, dry spell, and some of that turf may have bought the farm as well. Yesterday we had only an inch and a half of rain, and yet flooding still occurred where soils were hard from drought conditions. Like Roseanne Roseannadanna used to say- “It‘s always something!”.

I will not especially miss this summer, with its extended heat and awful humidity. I intend to enjoy the cooler weather and especially the cooler nights. And may I never complain about the winter again. Like that will actually happen…

Every year at the UConn Home & Garden Education there are a few topic of interest that we get a lot of calls about. Several years ago we fielded a lot of calls about the drought situation in Connecticut that occupied many people’s thoughts in 2016. In fact, that encompassed two years as we started to feel the effects of it in 2015. On the tail end of the drought, and perhaps in part because of it, many parts of the state were visited with an infestation of gypsy moth caterpillars. When we have a wet spring the fungus Entomophaga maimaiga, a natural control of the gypsy moth caterpillar, can flourish. The fungus overwinters as spores in leaf litter and in the soil. It then reactivates in the spring when there is sufficient rainfall. Although we were receiving an adequate amount of rain by 2017 it happened to occur a bit late for the fungus to be fully effective against the voraciously feeding caterpillars. So the summers of 2016 and 2017 were dedicated to answering many questions about the gypsy moth caterpillars and the damage that they wreaked.

As those two events have wound down a new concern arose for many of our clients. Thanks in part to press releases and an interview that aired on NBC CT in June the giant hogweed, Heracleum mantegazzianum, (below images) jumped to the front of the queue. The Connecticut Invasive Plant Working Group (CIPWG) issued a warning about this invasive species which was first spotted in Connecticut in 2001. Most of the populations of giant hogweed are under control and none of the reported sightings in 2018 were positive.

There are many look-a-like plants and it is those species that we are asked to identify. Starting in early-June calls and emails began to come in to identify large herbaceous perennials that were striking fear into Connecticut residents. This is in part due to the pretty noxious nature of the giant hogweed sap. Within 24-48 hours after skin has been in contact with the sap painful blisters may appear in individuals that are sensitive to it. Three things need to be present for the reaction known as phytophotodermatitis to occur. First, direct contact between the skin and the sap. Second, the skin must be moist as from perspiration, for example. Third, the contaminated area must be exposed to sunlight. If you are working in an area that contains giant hogweed it is easy to imagine that all of the criteria could be easily met.

Before attempting to remove giant hogweed from an area the first step should be positively identifying it. As I mentioned earlier, there have not been any confirmed sightings in Connecticut yet this year. It may be that the suspected plant is one of the following instead.

The first plant that is most commonly mistaken for giant hogweed is fellow member of the Heracleum genus: cow parsnip, Heracleum maximum, (images below). Unlike giant hogweed which was introduced to the United States 100 years ago from the Caucasus region of Central Asia, cow parsnip is native to North America. A tall herbaceous perennial that can reach up to 10 feet in the shade, nowhere near the 18 feet possible height of the giant hogweed, cow parsnip bears its flowers in in the flat-topped or rounded umbels that are characteristic of other members of the carrot family, Apiacea. Both species have compound deeply-lobed, toothed leaves but the cow parsnip lacks the red veining and leaf stalks common to giant hogweed. Cow parsnip also contains chemicals that cause phytophotodermatitis.

The next most common look-a-like is angelica, (below images). A first cousin once-removed, it shares its family, Apiaceae, with the giant hogweed and cow parsnip but is in the genus Angelica. Angelica grows 3-9 feet tall and also has large umbel flower heads. The compound leaves of angelica are what distinguish it from giant hogweed as they are bipinnate, meaning that they are compound leaves in which the leaflets are also compound (think honey locust leaves). Often used as a medicinal herb, angelica is the least toxic of the hogweed look-a-likes although it may still cause a skin reaction.

Queen Anne’s lace, Daucus carota, (below images) takes compound leaves one step further to tripinnate, having pinnately compound leaves that are bipinnate. The more levels of pinnation, the more delicate the overall effect. The airy-looking leaves of D. carota are what give it the ‘lace’ part of its name and are similar to its subspecies, the domestic carrot. Queen Anne’s lace has an umbellate flower head atop a much slimmer stem than giant hogweed, cow parsnip, or angelica. The sap from the leaves and stems can cause a phytophotodermatitis reaction although the flowers are used to make jelly similar to the yarrow jelly from our June 26th blog post.

The native Lactuca species includes wild lettuce (Lactuca Canadensis),

prickly lettuce (L. serriola), hairy lettuce (L. hirsute), and the blue lettuces (l. biennis, L. floridana, L. pulchella, L. villosa).

These tall plants start out from a basal rosette of leaves and can grow to 7 feet tall with large alternating broad leaves.  They have pale blue insignificant flowers compared to the dense clustered heads of the previous plants.

Finally, giant ragweed, Ambrosia trifida, has also made a plant identification appearance.  This 6-foot tall annual herb is a noxious weed that has become invasive in other parts of the world as it out competes native species in much the same way that the giant hogweed has here.

As plants and seeds have spread across the globe through human, animal, mechanical, or water means many species have landed in non-native locations and taken root there. If you are a fan of podcasts, check out the Infinite Monkey Cage’s Invasion episode where scientists and comedians take a look at the problems caused by alien (plant) invasions.

“What dreadful hot weather we have! It keeps me in a continual state of inelegance.” – Jane Austen

What a strange summer we have had so far in New England! I almost thought of going to Florida to escape the heat and humidity. It has been hot and humid, no doubt, but it is August after all, and things are coming along nicely in the out- of-doors. This time of year there is enough good stuff going on in the landscape to overcome any weather difficulties we may be experiencing, so let’s plod on out and see what’s happening.

As we head on into the mid= summer, most garden buffs are by now reveling in the abundance of hydrangeas that are now in bloom. The dwarf ‘Little Lime’ is one of several panicle Hydrangeas that have nice full-bodied lime green flowers that pack a visual punch in the landscape. ‘Little Lamb’ is another of the smaller panicle hydrangeas, this one also having a compact form with pure white, ethereal blooms that give it its name.

Hibiscus are also blooming now, with their outstanding large, colorful flowers that really provide some visual excitement in the garden. I came across a nice hedgerow type planting that made a nice privacy screen along a sidewalk. I am not really a hibiscus fan, but a pink- flowered one popped up in my garden, and looks so great there that I guess it can stay. I wonder if someone snuck it in there to get me to have kinder thoughts toward these plants…

On the wild side, the sweet- smelling Clethra alnifolia is in full bloom and is attracting all types of bees, beetles and butterflies. Look for this small clump-forming shrub in any areas where soils are moist. The white flower spikes are very fragrant, so you can tell where Clethra are long before you actually see them. Groundnut vine is also blooming now, with its pea-like pink flower clusters dangling from its twining stems. Often found twining itself around goldenrods and blue vervain, it is always fun to come across this plant.

The barn swallows that are partial to building their nests on the eaves of our equipment building have had their second brood of the year, as have bluebirds. Hopefully that will exit the nest soon and mom and dad can have a much needed rest in the near future. There was a female wood duck taking her brood on a tour in a large beaver pond the other day.

I came across a wild grape that had one leaf covered with interesting cone- like galls formed by the grape tube gallmaker midge (Schizomyia viticola). This is a harmless gall, and only affected one leaf on the entire grape plant. Looks like a bunch of tall red, skinny gnome caps were set on the leaf.

Combing through garden centers for great plants is always enjoyable when you find something like the Blackberry or leopard Lily Belamcanda chinensis. Star shaped flowers only 2 inches wide are heavily spotted with red, while foliage is sword- shaped. The flowers appear in late summer and bloom until frost, so this is a good plant to spiff up areas where other perennials are fading into the sunset.

Interesting plants suitable for containers are agave and other succulents. I saw a good size Agave colorata recently which was very striking in appearance. Its leaves are thick and powdery blue- gray with unusual cross- banding designs on them, plus leaf edges have brown teeth tipped with spines. A spectacular plant!

Caterpillars this time of year are larger and, in my opinion, more interesting than the early season caterpillars. One favorite is the brown- hooded owlet, which is a sports a rich array orange, blue, yellow and red. Look for this caterpillar on goldenrods, where it feeds on flowers and flower buds.

If you want a nice surprise, with a little careful handling you can check inside folded stinging nettle leaf shelters and may find either caterpillars of the comma or red admiral butterflies, or the chrysalis of the red admiral.

The skies can provide some viewing that is better than any television show. Thunderhead clouds can provide some drama as they develop on hot and humid afternoons, and may provide further excitement in the form of thunder and lightning, and rainbows may follow. We can have remarkable sunsets any time of year, so don’t forget to have a look at the sky around sunset. August is also a great time for early morning fogs as well, especially when we have had a humid night. Getting up early does have its good points…

praying mantid 2

Praying mantids have hatched and are busy staking their claim in all areas of the garden looking for any insect to eat. They are fun to watch and photograph. So glad I noticed their egg masses and relocated them when cutting back the garden last fall.

clove current berries

The clove currant is producing berries, first green then ripening to black. The birds are eating them faster than I can take a photo them almost. Good plant for wildlife, and a hand-me-down plant from my husband’s grandmother’s home. The Latin name is Ribes odoratum for those doing a search to find one.

swallowtail butterfly

This swallowtail butterfly was very busy feeding on the nectar of the very floriferous bottlebrush buckeye blooming on campus. Bottlebrush buckeye, Aesculus parviflora, is a fabulous, large shrub which sends up panicles of white flowers with red anthers and pinkish filaments.

spinach bolting 2

The summer’s heat is causing the cool weather crops of the spring to bolt and go to seed. Once this happens, the leaves become bitter and plants should be pulled and composted. Planting fall crops of carrots, beets, peas, kale or beans make good use of then now available space in the garden.

Robber fly

This robber fly was resting in the garden, probably waiting for an easy insect meal. They are predatory on all types of insects and considered a beneficial insect.

cross striped caterpillar on cale

If your kale or other cole crops are being eaten and showing a lacy appearance of holy leaves, look for the cross-striped cabbage worm. One caterpillar can eat quite a lot. Bt is a good control measure when they are small, or insecticidal soap. Rotate where brassica plants are located next year, and grow under a row cover to keep the adult moth from laying her eggs on the leaves.

garlic

Garlic is ready to be harvested during July, once half of the leaves have turned brown. After carefully loosening the soil with a spade, pull the garlic bulbs by the stems and dry on an open rack in out of the sun and under cover for three weeks. A shed or garage are best for the drying. After they are dry, brush off the dirt, cut off the roots close to the bottom of the bulb, and cut back the stem end leaving about one inch. Store in the home in a dry, dark spot. Save the largest bulbs for planting next October through November.

gypsym moth females and egg masses

Gypsy moth adults are busy mating. Females do not fly, only able to crawl. The males are flitting around, flying to females to mate. Females will lay the buff colored egg masses which will last through the fall, winter and spring, to hatch next summer. Egg masses can be  crushed or scraped into a container of soapy water.

“Fortunate is the man who knows how to use yarrow in the last days”
Attributed to Brigham Young

Brigham Young was born into a farming community in Whitingham, Vermont in 1802. Like many people at that time he would have been well-acquainted with the use of plants for medicinal purposes. Yarrow in particular has many medicinal and culinary purposes that have used for centuries. Its astringent properties led to it being used to reduce the flow of blood from wounds and the names herbal militaris, staunchweed, allheal, and bloodwort. In fact, legend says that it was used by Achilles’s soldiers on the battleground of Troy. It is that legend that gave us the Latin name for yarrow: Achillea millefolium.

It interested me to learn that since the second century BC yarrow has been used by the Chinese for divination of the I Ching. Diviners prefer dried stalks from locally gathered yarrow as they feel they will be more in-tune with it. Even better are stalks harvested from spiritually important sites such as a Confucian temple. This practice of divination is still widely used today.

In North America yarrow was used by many Native American peoples. The Navajo chewed it to relieve earaches, the Cherokee made a tea to reduce fever and aid sleep, and the Ojibwe, in addition to those uses, burned it for ceremonial purposes. They also gave it to their horses as a stimulant although the ASPCA says that yarrow is toxic to horses, dogs, and cats. For a small number of humans, it occasionally causes allergic skin irritations and photosensitivity.

For the rest of the population, yarrow has so many diverse uses. Let me start with its attractiveness to pollinators. As an umbrellated plant, that is one that has a flower head that is in the form of an open, flat-topped cluster, it is a convenient landing pad for many insects.

These white, yellow, or pink flower heads contain masses of minute, 5-petaled flowers. It is this that gives yarrow the second part of its Latin name, millefolium, or thousand-leaf or petal.

Millefolium can also refer to the many very fine, feathery leaves that adorn the yarrow plant. These lacy alternately arranged, fern-like leaves, can be dried and then steeped in hot water for a ‘tea’. The stripped stems can be boiled in water for 20 minutes and then sautéed in butter as an addition to a salad.  Yarrow leaves and flowers were part of an herbal mixture called gruit that was used as a substitute for hops in the production of beer during the Middle Ages, mostly in the Netherlands, Belgium, and western Germany.

Leaf close-up

In researching yarrow, I came across several mentions of yarrow jelly so of course I needed to make it. I harvested 2 cups of flower heads early one morning, rinsing them and then placing them into a steeping carafe along with freshly boiled water.

I let the mixture brew for an hour before draining it through two layers of cheesecloth. No need for any little insects to be involved in the jelly-making process.

The jelly-making method that I use calls for adding lemon juice and calcium water to the strained liquid. To my astonishment, as I stirred in the lemon juice into the yarrow ‘tea’ the color changed from a dull amber to pink! It turns out that the acid in lemon juice will turn pink when a molecule called an anthocyanin is introduced to it.  Anthocyanin is present in red, blue, and purple flowers including the deep pink yarrow that I used.

Unfortunately, the resulting cooked jelly did not retain that pink color that I love in the blossoms and that is so attractive to insects like the drone and hover flies that recently visited.

A tiny grasshopper nymph  in the species Melanoplus let me get very close to capture his image, jumping away only at the last second.

Grasshopper nymph

Looking a bit lower and deeper into the foliage I saw the tiniest of field ants moving among the feathery leaves. He was not alone.

Field ant (Formica spp).

Nestled in the leaf axil was a spittlebug. No bigger than the head of a pin, the adult Clastoptera lineatocollis was well hidden.

Spit bug 3

The video is of a spittlebug nymph feeding on another plant, covering itself with the foamed-up plant sap.

The foamy ‘spit’ not only hides the nymph from predators and parasites it provides a unique protection from the light that might dry it out.

Further up, an Eastern harvestman spider, Leiobunum vittatum, lay in wait for an unsuspecting red spider mite, Tetranychus urticae. I hope that the harvestman enjoyed his lunch for although one spider mite won’t do too much damage as it sucks out the contents of individual plant cells, an infestation of hundreds can seriously affect the vigor of a plant. Its good to see that a beneficial spider is taking care of that for me. Other beneficial insects that are attracted to yarrow include lady beetles and parasitic wasps such as the Braconid wasp.

If you don’t have yarrow in your flower beds yet I recommend it as a lovely, delicate-looking perennial that brings a touch of antiquity to any site. And here is one more thought from Brigham Young that speaks to the gardener in all of us:

“Beautify your gardens, your houses, your farms; beautify the city. This will make us happy, and produce plenty.”

Susan Pelton

According to the language of flowers, the rose belongs to the month of June symbolizing love and passion, gratitude and appreciation. Well I am passionately in love with and greatly appreciate all of June’s flower blooms, including roses.

Rose, red climbing-1

Roses can be found in home gardens, public gardens and even commercial parking lot plantings, usually as tough shrub rose varieties needing little care. Hartford is the proud location of Elizabeth Park, the oldest municipal rose garden in the United States established in 1904. Within its boundaries are beds and arches filled with hundreds of rose plants loving tended by professionals and volunteers, all taking pride in creating a beautiful and scent filled space for all to enjoy. http://elizabethparkct.org/gardens-and-grounds.html

 

Check rose plants carefully as gypsy moth caterpillars are feeding on leaves currently. Hand pick off and kill the little buggers by squishing or dropping in a container of soapy water. Signs they were there and left are shown by them leaving their shed exoskeleton after they molt.

Not all roses are a considered a ‘bed of roses’ or a good thing. The multiflora rose, Rosa multiflora, is an invasive species of rose, overtaking and displacing native plants. It was introduced to the U.S. from Asia in 1866 for use as rootstock and later widely planted as hedgerows and living fences.  Due to its very thorny nature, animals did not attempt to cross. Multiflora roses can be identified by its fringed petioles which differ from most other rose species. When in mass  blossom, the make the June air incredibly sweet.

A few other fabulous flowers caught my eye and camera lens this month so far. Lunchtime walk on the Storrs campus I found an unusual shrub in front the Castleman building. False indigo, Amorpha fruticosa, was sporting spires of purple and orange flowers similar to butterfly bush. I had never seen it before, and after researching its identity, I am glad I haven’t as the CT Invasive Plant Working Group has it listed as ‘Potentially Invasive’. It seems well behaved in the restricted spot surrounded by buildings and pavement, but pretty still the same.

The perennial Helen Elizabeth Oriental poppy is a lighter pink, eschewing the brazen orange color of traditional oriental poppies. Helen Elizabeth is softer on the eyes and blooms a little bit later than the orange one.

 

Annual poppies are just beginning to bloom in my garden. If you let them go to seed and collect the seed once the pods go brown, dry and rattle, you will have an incredible amount of seed to save, share or spread the beauty in other areas.

 

Foxgloves, Digitalis sp, are shooting up their towers of flowers in different colors. Some species are biennial and others are perennial. The spots on the throats of the flowers are believed to be nectar guides showing the bees and other pollinators the way in to find the location of the nectar.

Visit local, independent garden centers and nurseries for unusual plants not found in the big box stores or chain centers. I found the annual Popcorn Plant, Cassia didymobotrya, whose leaves smell like buttered popcorn when stroked, at Tri-County Greenhouse on Rt. 44 in Storrs Mansfield. A treasure trove of unknown annuals and surprising perennials, and large variety of tomatoes and vegetables were all over the sales yard. I especially love the philosophy of the place hiring very capable people with intellectual disabilities along with some great horticulturists.

June also brings disease and insects to the garden. A few of the things we are seeing from submissions for diagnosis to our office are shown below. Azalea galls were sent in from South Windsor and are being reported around the state. The fungal disease, Exobasidium vaccinii, develops from an overwintering infected plant part of azalea leaf, twig or flower, and malforms the plant tissue into a curled and thickened gall.  As the gall ages it turns white releasing more spores to infect fresh tissue. Control should be to hand cut off and destroy galls before they turn white.

Azalea gall, b.zilinski 2

Another sample image sent in were sweet birch leaves with bright red growths called Velvet Galls. These red patches are soft felt-like growths made by the plant in response to  to wall off the damage by a tiny eriophyid mite feeding on the leaves. The red patch is called an erinea. Unsightly while still being pretty, the damage is considered only cosmetic and causes no lasting harm to the tree. Thanks to Jean Laughman for her photos.

Another great photo was sent in by Shawn Lappen for insect identification. The Dusky Birch Sawflies were striking a classic pose while eating the heck out of the leaves of a birch tree. Sawflies are stingless wasps whose larvae are plant feeders. The larvae are not caterpillars as this insect is not in the butterfly and moth order of Lepidoptera. Feeding damage usually does not cause much damage to a tree in good health. If control is needed, insecticidal soap will suffocate the larvae when sprayed on them.

Golden tortoise beetles are attacking morning glory and sweet potato plants. They look like a little drop of gold but their beauty belies their destructive nature. Hand picking and dropping into a container of soapy water will kill them quickly.

Golden Tortoise beetle

Be on the lookout for Luna moths during the month of June. It is one of the largest silk moths and is attracted to lights at night. After mating, the female will lay her eggs on one of the host plants for the caterpillars including white birch (Betula papyrifera), persimmon (Diospyros virginiana), sweet gum (Liquidambar styraciflua), hickories (Carya), walnuts (Juglans), and sumacs (Rhus). The photo below was sent in to us last June 4 by A. Saalfrank.
