“By all these lovely tokens
September days are here,
With summer’s best of weather
And autumn’s best of cheer.”
–   Helen Hunt Jackson, September, 1830-1885

September brings a wealth of inspiration to the senses. Leaves of Virginia creeper are red already, there is the intoxicating scent of wild grapes in the pre-dawn foggy mornings, asters and goldenrods bring colorful splashes to the landscape and sunsets may fill the cooling sky with brilliant deep reds and oranges. Tree Hydrangeas, Hydrangea paniculata, had a great year, and many still have panicles of colorful flower heads. While many plants and insects are winding down to an early retirement, there is still a lot going on in the great outdoors.

It may be the time of year for oddities, now and then. For instance, there is a horse chestnut outside our office on the Storrs campus that has several flowers in full bloom this week. While many shrubs and fruit trees, like cherries and azaleas, may have a secondary bloom in the fall after rains, cool weather with a late autumn warm spell following, a chestnut blooming at this time of year is a more remarkable event. A bumblebee spent time visiting the flowers, so a second round of pollen and nectar is a bonus in that quarter.

Red-headed crickets are a first for my gardens this September. These small crickets have a distinctive red head and thorax, iridescent black wings, and yellow legs.  At first glance, they really do not appear to be crickets because of how they move around vegetation. They also have large palps with a paddle-like end that they wave around almost constantly, giving the appearance of mini George Foremans sparring in the air before a fight. Found mostly only three feet above the ground, they have a loud trill and are usually more common south and west of Connecticut.

While visiting Kent Falls recently, I came upon a few small clumps of American spikenard. Aralia racemose, loaded with berries. Highly medicinal, this native plant is found in moist woodland areas such as along the waterfall trail at Kent Falls. Roots are sometimes used as a substitute for sarsaparilla, another Connecticut wildflower.

Many migrating butterflies like monarchs and American Ladies are on the move now and may be found on late season flowers like butterfly bush, zinnias, Tithonia, Lantana, cohosh, goldenrod, asters and many other flowers. In annual plantings where I work, honey bees are especially abundant on Salvia guaranitica  ‘ Black and Blue ’  right now.  And while many butterflies and bees can be found on various butterfly bush cultivars, the hands on favorite seems to be the cultivar ” Miss Molly” which has deep red/pink, richly scented flowers that attract hummingbirds, flower beetles, fly pollinators, people and bees galore. This is a great addition to a pollinator or butterfly garden. Other late season bloomers for our native insects and butterflies are black cohosh and Eupatorium  rugosum, (chocolate Joe-Pye weed), as well as asters and goldenrods.

Snapping turtles are hatching now.  The other day while mowing fairways, I spotted long dew tracks and there at the end were two little snapper hatchlings. Very soft upon hatching, they are often heron chow, and these little turtles will travel long distances to find a good habitat.

Every day at my house, we engage in a “Where is Waldo?” type hunt in the backyard gardens. What we are looking for are the tiny gray tree frogs that are hanging out on certain plants during the day. Snapping up any insects that get too close, these guys are a lot of fun to watch and look for. Most of ones we are finding are green, and are slightly larger than a thumbnail right now.  It gives us all some free entertainment before the leaves fall and we move on to- raking leaves…

Katydids, crickets and sometimes tree frogs are making a racket at night. Although really not unpleasant, to me, they are loud. But more enjoyable to listen to than the neighbor’s barking dog…I found a katydid eating a hyssop flower recently, but who cares about that this late in the year?

Bees are having their last hurrah now as the blooming season winds down. While native goldenrods and asters are important food sources of food for late season bees and wasps, there are many garden plants that are important nectar and pollen sources as well. In my own garden, I have two hyssops- anise and blue giant hyssop. There were bumblebees and honeybees that went on both, but there were small bees that preferred only the anise hyssop. These bees were very noisy, and hovered near flowers before landing, behaving like hover flies. Most likely these bees were in the Megachilid genera- the leaf-cutting bees. Abdominal hairs collect the pollen in these species and may take on the brilliant colors of pollen from the flowers they visit.

As the season winds down, there are still some caterpillars to be found, like the beloved wooly bears and other tiger moth cats like the yellow bear. A spotted Apotelodes was a good find. A robust, densely hairy caterpillar, this large fellow is notable for three sets of long hairs called “pencils” along the dorsum, and for its equally conspicuous red feet, making it look like it is wearing five pairs of little red shoes.

And just for fun, next year consider planting a candy corn vine, Manettia inflate, on a small trellis.  An annual vine, flowers last well into the fall before the first killing frost. This South American native has tubular flowers that resemble candy corn, and they are a favorite of the hummingbirds (and myself!) in my backyard.

Germander

Germander Plant, CQuish photo

Germander is an unusual perennial herb which makes a great edge of the border plant. Its Latin name is Teucrium chamaedrys. Germander takes well to shearing to form a garden border or knot garden, making it a good alternative to boxwood plants. Size of each plant will be about 10 inches tall with equal spread. It has also been used as a bonsai plant with great results.

Germander is native to Europe, Syria and the Greek Islands. It likes a pH of 6.3 and well-drained soil. Plant will produce pink blooms sporadically from mid-summer through the fall. Leaves have a strong unusual scent when crushed, and have traditional been harvested for medicinal properties to treat a variety of ailments in times before modern medicine. Although some folks still practice herbal remedies, we cannot recommend them in this forum as we are not doctors. Cut branches make a lovely wreath for decoration and freshen the air inside.

Leaves are dark green, tiny and have serrated edges giving a fine overall texture to the plant. Germander is in the mint family, but behaves well in the garden, not spreading much. It also is not liked by deer due to its scent, and insects and diseases rarely attack adding to its attributes. Prune before new growth starts in the spring.

“The brilliant poppy flaunts her head

Amidst the ripening grain,

And adds her voice to sell the song

That August’s here again.”

–  Helen Winslow

 

August means summer is heading for a subtle change. Evenings begin to get cooler, skies are less hazy, most birds are getting a break from chasing fledglings all over creation, and the sounds of crickets and katydids during the night have replaced the trilling of the tree frogs. Bats are seen more frequently now as many moths and other late summer night- flying insects are abundant. Trees and shrubs have ripening fruit, deer are eating acorns already and, to top it all off, we just had a solar eclipse. Now is a great time to get outside and see what is happening in the garden and in the wild.

The tiger bee fly, Xenox tigrinis is a very large fly that can be seen flying about now. About the size of a quarter, this fly may fly low over lawns and can be mistaken for a wasp. It has large white markings at the end of its abdomen and they really stand out against the black color of the rest of the abdomen, resembling a bald faced hornet somewhat as it flies around, , apart from its size. Female tiger flies lay eggs near carpenter bee tunnels, and its larvae will eat the bee larvae that are developing within.

One of our larger spiders is the black and yellow orb weaver, Argiope aurantia. Commonly known as garden spiders, orb weavers are frequently found in gardens, meadows and fields. Their web has a zig-zag pattern at the end of a  thickened strip of silk that and may signal birds so that they see it and avoid flying through the web, thus saving the spider from major repair work. Who knows? Other creatures seem to miss that cue and end up as little morsels in the food “web”.

Another orb weaver, the arrow spider (Micrantha sagittata), is much smaller the black and yellow one, and is one of only three Micrantha species found in North America. It has an interesting web composed on a rather permanent frame structure and then the orb section is built inside the frame at dawn every day. In the evening, the spider will consume the orb part of its web and have to start anew the next morning. The whys and wherefores of this behavior is one to be marveled at, if not at all understood by mere mortals.

Butterflies are having a banner year- even giant swallowtails are being seen in northern Connecticut as of late. I just peeked inside the old stinging nettles leaf shelter of a red admiral butterfly caterpillar and found its chrysalis inside. One way to avoid predators is certainly to make oneself scarce. Monarchs, spicebush and tiger swallowtails and American ladies are abundant in numbers this year. Good plants for late season butterflies, especially migrators, are boneset, Joe-pyes, goldenrods, mountain mint, lantana, petunias, impatiens and bluebeard (Caryopteris). Mints and bluebeard are excellent for late summer pollinators as well. My gardens are humming with bee and butterfly activity right now as I have most of these plants in flower.

Venturing out where forbs and small shrubs abound, you may run across the groundnut, Apios americana a native perennial vine that right now is in flower. The sweet- scented flowers are wisteria- like in form, appearing in small clusters along the vine. Found climbing among small shrubs and perennials like dogwoods, goldenrods and ferns, this plant is sometimes only noticed because its flowers are so striking in both color and clustered among a green background form the plant derives its name from the edible tubers that were consumed by native Americans and early settlers.

Cardinal flowers are also in bloom along watercourses now, and their brilliant dark red blooms and rich nectar attract hummingbirds. Along with jewelweed, cardinal flower is a great source of food for these energetic little birds. If you wait long enough when these plants are flowering, a hummingbird or two should make an appearance.

Giant silkworm moths are putting in a second appearance this year, meaning a second or partial second generation of caterpillars will soon hatch. Over the last three weeks, Polyphemus and Luna moths have been seen, and there are fourth instar Promethea caterpillars out. Since the giant silkworm caterpillars take so long to reach the pupal stage, they may run out of foliage as many of the trees they feed on may shed their leaves before they can form cocoons.

And be careful out there! This past weekend I found two saddleback slug moth caterpillars in two different areas of the state, both on foliage not far off the ground. Though small, these caterpillars have many urticating spines that can cause a sensation like being stabbed with hundreds of tiny red-hot hypodermic needles.

As we move into the end of summer, sunrises and sunsets should be more colorful as the skies get cooler and particles high in the atmosphere scatter the blue light to our west and east as the sun sets or rises. To the early bird, then, may you see a spectacular sunrise.  And to the observer at eventide, may you be rewarded with an equally breathtaking sunset.

July in Connecticut is an exciting time for me because of all the good wildflowers and insects that abound at this time of year. Insects get more interesting in summer and late summer, especially caterpillars that feed on older leaves. Plus, many birds have fledged their first brood by now, so the young birds are scattering around keeping their parents busy. Flowering trees are few, but in July sumacs, tree-of-heaven and the hardy silk tree bloom from mid to late July.

While July is hot and sometimes dry, we have had an abundance of rain so far this year. This is a really good thing because the gypsy moth caterpillars severely defoliated many trees that now need rainfall to help put out new leaves before autumn. We hope next year will have less of these pests, especially since many of the caterpillars were killed by either a fungus or a virus.

Wildflowers like early goldenrod, swamp milkweed, bouncing bet, monkeyflower and nodding ladies tresses are in bloom now. And the peculiar Indian pipe, Monotropa uniflora, has popped up, especially under white pines. It occurs in rich, damp forests where there is abundant leaf litter. While this plant may appear to be a fungus due to its white color due to a lack of chlorophyll, it is not. It survives in a mutually beneficial relationship with a fungus in the soil where it grows. Blue curls are an interesting wild flower that can form colonies in sandy, infertile soils. Bloom time is normally late July through mid- August. Check out damps areas for stands of swamp milkweed- one of the prettier of the milkweeds, to me. All kinds of butterflies and bees may be seen getting nectar from its flowers.

This year Eastern red cedars have put out a bumper crop of fruit, unlike the dismal amount of blue berries produced last year. This is good news for migrating birds like the yellow-rumped warblers that rely of this food as they fly south. And, of course, the cedar waxwings that derived their name from their fondness for cedar fruit, will enjoy any fruit that remains after the migrators have departed.

Monarch caterpillars have been spotted, some in later instars, so that is good news for this favorite butterfly. Swallowtail caterpillars are also in later instars, and will have a second generation of butterflies later this summer. Check out small aspens for the caterpillar of the viceroy butterfly. This bird- dropping mimic will win no beauty contests, perhaps, but it is a good find nevertheless. Sphinx and many other moths are flying now, and bats are enjoying them during their night forays. Some of the geometers, or inchworms, have very pretty moths to make up for the drab larval stage.

If anyone had their Joe-pye weed leaves chewed badly, it may have been the work of large populations of dusky groundling caterpillars. They are done feeding now, but keep an eye out next year if you had this problem. And aphid populations swell at this time of year as females give birth to live young by the truckloads. Sunflowers and milkweeds are just two of the plants that can have aphid populations that are very high.

Enjoy yourselves out there in the garden, park, or wilds. Look up and down and all around, for things of interest that abound this time of year. And listen for the katydids as they start singing during the hot, summer nights.

Spring being a tough act to follow, God created June.

This spring took forever, it seemed, to warm up, but it did, and just in time. Rains provided a boost to plants that suffered during the drought of last year, and dogwoods, crabapples, azaleas and rhododendrons had fabulous flowers this spring. But now June is here, and yesterday marked the first day of summer, and so we move on to the warmer weather and all it brings with it.

elderberry blossoms 2011

Elderberry flower head

Native elderberries are in full bloom right now and many bushes are covered with the large, white flower clusters. Later on, the dark purple fruits will provide food for many birds and mammals. While edible for humans, and high in vitamin C, most people do not care for the raw fruits, but may make jam or pies from them. And mountain laurels are still in bloom now as well. Some cultivars, such as ‘Kaleidoscope and ‘ Firecracker’ have striking red flowers. Dewberry, a native berry that forms mats sometimes as it creeps along the ground, is in bloom now, and its flowers are important food sources for many native bees and butterflies. Soon to come into flower are the native Canada lily, Indian pipe and native wood lilies. Venus’ Looking- glass, Triodanis perfoliata, is a native purple wildflower that has its flowers along the stem at the leaf axils. Poke milkweed, Asclepias exaltata, should be blooming now. This native milkweed grows well in wooded, shady areas. Flower heads dangle down, unlike those of most milkweeds. The white flowers are attractive to several moth pollinators.

Several insect pests are making their presence known. The infamous 4-lined plant bug, a lime green adult with 4 black lines down its back, leaves behind diagnostic feeding damage that later on will look like black angular leaf spots. They are cosmopolitan in plants they will eat. This year they have been reported feeding on many herbs, dandelions (who cares?!), sunflowers, sedum, and the list goes on. Also, both the Colorado and false potato beetles are mating as we speak, and they seem to be heading for a banner year, population –wise. So crush the eggs as you may find them on any of your nightshade family plants like tomatoes and peppers. Be careful not to crush any lady beetle eggs, though, as the larva will feed on those of the potato beetles.

On a walk along a power line yesterday, I was delighted to see two visitors from the south- common buckeye butterflies. I have not seen these occasional visitors since Hurricane Sandy, so this a good butterfly to keep on the look-out for. Red- spotted purple, viceroys and American lady butterflies should be in the process of laying eggs now, if they haven’t already. I found several tiny spicebush swallowtail caterpillars also this week. Check out your dill, fennel or parsley, because the black swallowtail butterfly may have laid an egg or two on them, and the caterpillars may have hatched out.

Swamp milkweed leaf beetles are easy to spot with their red and black elytra. Not pests, these chunky beetles are just a colorful splash on a green background. Pine sawyers, longhorn beetles commonly mistaken for the invasive Asian long-horned beetle, are active now. They will often visit newly stained decks until the stain dries out. Dogwood calligrapha beetles, striking in their spiffy black markings on a white background, are out and about on native dogwoods now.

There are many birds that are now fluttering around trying to keep up with newly fledged young.  Catbirds, robins, red-tailed hawks, Carolina and house wrens, Bob-o-links and some sparrows have a clutch early and some species, like the ubiquitous robins have a second brood. Fledglings are often very loud as they beg for food, and get louder still as mothers withhold food briefly, to teach them how to fend for themselves.

we recently had a visitor to our office. A green bullfrog somehow landed in our window well and could not escape. So we managed to catch it and Joan Allen walked it to a nearby pond. Another bit of excitement at work.

As you venture out into the landscape, I hope curiosity will get the best of you, causing you to turn over leaves looking for insects, watching birds as you see and hear them, and bending over to see what is lurking on the ground by your feet. In such a way we become more interactive with the environment and thus, less frightened or at least dismayed by new discoveries. Look stuff up when you find it. Curiosity did not kill the cat, nor will it do likewise to people. Nor has asking questions ever done any harm, at least as far as I know…

Like many landscaped yards in Connecticut our property has boxwood adorning our front yard, planted more than 30 years ago. This shrub is usually a minimal maintenance woody ornamental plant. It requires a bit of shaping once a season even though its slow growth habit doesn’t send out the random foot-long shoots that its neighboring Japanese maple does. In fact, the amount that is trimmed off is more like a ‘shaving’ of its foliage and the easiest way to collect the clippings is to place a tarp beneath the shrub (the tiny pieces of leaf are almost impossible to rake it up). We tend to do the shaping of the shrubs in the landscape somewhere near the end of June and beginning of July. I remember one year (and I’m sure that my daughter will never forget) trimming them on a hot humid day where we ended up wearing bits of foliage that stuck to our damp skin!

Over Memorial Day weekend this year as I walked past the boxwood that borders our driveway I was surprised to see it covered in a white fuzz. I stopped in my tracks for a closer look. Up and down the stems and in the leaf axils was a fluffy white coating that dispersed like a powder into the breeze when I touched the shrub.

IMG_20170530_074456085

Using a macro lens, I took successively closer images until what looked like just white fuzz became individual clumps and then minute insects. These are the nymphs of the boxwood psyllid and the white fuzz was waxy strands of their crystallized honeydew secretions that is also called ‘lerp’. Yes, that is a real word. Boxwood psyllid (Psylla buxi) are in the family Homoptera, a suborder that also includes aphids, scale insects, cicadas, and leafhoppers.

The tiny orange eggs of the boxwood psyllid overwinter in the bud scales of the boxwood and will hatch when the temperature reaches 80 degree days, around the same time that the buds open. Degree days are an accumulative measurement that allow the prediction of insect appearances and plant blooming. For more info on degree days, visit the Cornell University site: Network for Environment and Weather Applications.

Enfield, CT reached 80 degree days on May 18th this year and between then and mid-June when we accumulate 300 degree days the psyllid nymphs will go through 5 instar (nymph) stages. They mature into winged adults as they finish their incomplete metamorphosis. It was a bit slower this year due to the cooler temperatures. The adults will mate and lay their eggs under the bud scales, there is only one generation a year.

Most of the damage from the boxwood psyllid is in the leaf cupping that happens as the larvae feed. They have sucking mouthparts and the leaves curl around the nymphs as they feed, a rather tell-tale sign of their presence. The psyllid doesn’t do any substantial damage.

IMG_20170530_074410382

Meanwhile, another pest also made its appearance. A beautiful Goldflame honeysuckle, Lonicera x heckrottii that adorns our deck was getting its yearly aphid visit.

IMG_20150609_114321860

As a relative of the boxwood psyllid the feeding damage of this aphid (Hyadaphis tataricae) is very similar. They love the flower buds and can feed inside the bud before you can even know that they are there. Aphid damage will stunt the growth of the flower buds and prevent the honeysuckle flowers from blooming.

And that would keep us from one of the pleasures of outdoor dining on a summer evening: watching the hummingbirds visit the showy pink and yellow tubular flowers as they search for nectar. The hummingbirds dart in and out so quickly but they occasionally stop for a brief respite, barely bending the vining stem as they weigh so little, often less than 1/10th of an ounce.

Bees and other pollinators such as the Eastern Tiger Swallowtail (Papilio glaucus) also spend lots of time going from flower to flower on the honeysuckle. It’s important to keep these visitors in mind when dealing with pests such as the aphids. A systemic insecticide should never be used during the period when a plant is flowering. These pesticides will target all insects that feed on the plant’s sap, drink the nectar, or gather the pollen regardless of whether they are beneficial or not.

2012-07-26_13-27-04_844

A strong spray of water may dislodge aphids and psyllids or an insecticidal soap may be used. An insecticidal soap works as a contact pesticide and as such there is no residual insecticidal activity once the solution has dried. It must sprayed directly on the soft-bodied insects that it effectively controls. It also degrades quickly and will wash off leaf surfaces so that it won’t affect non-target insects, especially pollinators, or the lady beetles that consume the aphids in large quantities.

IMG_20170530_062842848

If you see (or have seen) psyllids or aphids you may want to do as I do and make a note of it in your calendar or your garden journal so that you can keep an eye out for them next year. Knowing when the aphids may show up on the honeysuckle gives me a bit of an edge in controlling them and allows the most blooms to come to fruition much to the enjoyment of humans, animals, and insects alike!

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

-Edwin Way Teale

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!
