Hardy silk tree

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.

 I love insects. They are amazing.”  Andrea Arnold  

The UConn Bug Week programs were held over the last week of July this year and for our particular Bug Week event on July 30, we started early on in the season acquainting ourselves with the world of insects and searching high and low for specimens we could find and then bring home with us to raise. While rearing insects, you learn a lot about what they do, what they eat, how they behave and what their life cycles are.

We had several bug hunts from early June on and went to specific areas searching for specific insects and any surprises that might turn up. Volunteers from the Master Gardener program spent two months looking for and raising insects in the hope that they would be available as live specimens for our event on July 30. Of course, many pupated and that was that. But we still had a lot of wonderful specimens to show all the people that attended our program. We had display boards that our volunteers made for their particular insects, and with the live specimens, people got to see insects up close and personal.

Our event was held at the Tolland County Agricultural Center, home to the Tolland County UConn Extension Office. There are over 35 acres of woodland, wetland and open environments, plus pollinator and butterfly- friendly plantings all over the property, so we were able to go outdoors and take advantage of all the gardens and wood lines to search for insects.

Among the insects we had for specimens and displays caterpillars of the clear dagger moth, mottled prominent, Virginia creeper sphinx, milkweed tussock moth, Monarch butterfly, stink bugs of all kinds, Imperial moth caterpillars (just hatching that day), tobacco hornworms on their favorite tomato host, beetles, John Suhr’s moth and butterfly collection plus the UConn Natural History Museum brought some specimens from their fabulous collection. Other specimens included red-lined panapoda caterpillars and orange-striped oak worm caterpillars. We also had two walking sticks which were found in early June when they were the size of a thumbnail.

We had three bug walks as well, and found interesting insects of all kinds- a Buffalo treehopper, leaf-footed bug nymph, silver-spotted skipper caterpillar, an apple maggot fly, a salt marsh tiger moth and a chickweed geometer moth just to name just a few. Many butterflies were also floating by  as we did our walks and we ended up seeing them again  when we got to the butterfly garden.

The TAC Center has one of the best butterfly gardens going, and has been well maintained by Tina Forsberg and Jean Laughman. It has a spicebush in the center of one side and on it we found 6 spicebush swallowtail butterfly caterpillars, one of which was only a couple of days old. Hummingbird moths, swallowtail, crescent, skipper and, brush foot butterflies were there, and we even found a tiger swallowtail egg on a small black cherry.

Thanks are in order for all our Master Gardeners and Master Gardener interns for a job well done. Without your efforts, this would not have been a success, nor as interesting an event as it was. Also, thank you Joan Allen, for your talk on vegetable insect pests, and Dave Colbert for bringing terrific specimens from the UConn Museum of Natural History.

After all our hard work raising insects and running around finding host plant material to feed them, and after many long insect hunts in 90 degree weather, I guess we were all happy, in a way, to see Bug Week draw to a close. My dining room table is no longer a laboratory and that is how it should be. And yet, I do miss the pitter-patter of tiny little feet…

Every now and then a couple of moths make an appearance in my kitchen or dining room. Beyond being a minor nuisance, they are a signal I have eggs, larva and pupa in some food product nearby. These moths are called pantry pests, specifically, Indian Meal Moths. Their Latin name is Plodia interpunctella. They feed on and infest grain products such as flour, oatmeal, cornmeal and just about any cereal. They are also known to eat dried fruit, chocolate, herbs and seeds. Insects are usually brought into the home unnoticed in food products from the grocery store and might occasionally fly in from an outside food source. Some unusual hiding and egg laying places have been reported to the UConn Home and Garden Education Center. The crumb tray of the toaster, the intake vents of stand mixers, in the pot holder drawer feeding on crumbs, in stored seeds for the vegetable garden and in the bottom of the holiday nut bowl are all additional sites of egg laying. Dry pet food and bird seed can contain Indian Meal Moths.

The lifecycle of Indian Meal Moth has four stages. The adult female moth will lay 60 to 300 eggs in or near a food source. The egg hatches into a larva within 2 to 14 days, then begins feeding for a varying number of days, depending on temperature and humidity. They then pupate during which they develop into a moth, emerge to fly around our kitchens, mate and repeat the cycle. Moths sometimes lay eggs on textured ceilings and at the corners where the wall meets the ceiling and on the underside of the cabinet shelves.

Signs they larvae are present in dry-stored foods are webbing and frass clumping food bits together and hanging from the top or sides of containers. In the case of the toaster tray, all of the crumbs were not loose but matted together in one lump. Adults and larva can chew through cardboard and plastic bags. It is best to store even unopened packages in hard sided plastic or glass containers. That way, even if you bring the insects in from the grocery store, they will be contained in the hard container.

Control measures include vacuuming and cleaning cabinets, examining food for any insect presence and removing. Soap and water will kill all stages of life of these soft bodied insects. Pesticides are not needed and not recommended indoors, especially around food. Keep cabinets clean, wipe up spilled food promptly and good sanitation practices will eliminate any food sources for any moths you might have missed. Placing suspected infested food containers in the freezer will kill the insects. The insects are not vectors of any human disease and will not harmful if eaten, but a little gross!
