“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.
