Eastern Tiger Swallowtails have two broods/generations each summer here. The first brood, which is airborne in May and June, is small in number, comprised of butterflies who survived the winter and early spring as a pupae in chrysalises.
The two moths that star in this episode are the Grapeleaf Skeletonizer Moth and the Virginia Creeper Clearwing. They are not related to each other (other than their shared Lepidopteranism), but they have a number of things in common.
Harvester Butterflies don’t stray far from the aphids that support their young because the adult feeds, not on flowers – its proboscis is too short to plumb the blossoms—but on the honeydew that collects on surfaces where aphids feed. their caterpillars eat meat, but not just any meat. Harvester caterpillars require wooly aphids, and Wooly Alder Aphids are a common host.
Eight-spotted Forester Moths is a smallish, flashy, day-flying moth that is often mistaken for a butterfly when it’s nectaring on flowers. Their caterpillars graze on leaves of plants in the grape family including wild and domestic grapes, woodbine/Virginia Creeper, peppervine, porcelain berry, and false grape in forest edges and sunny spots, and on vine-covered buildings.
There are moths whose larvae flirt with the aquatic environment by feeding on/in the stems of emergent aquatic plants, but there is also a small group of small moths whose caterpillars live underwater. Adult Two-banded Petrophila Caterpillars are found near the rivers and streams in eastern North America that their larvae inhabit. The hind wings of adult Petrophila moths have a row of black/metallic spots that make one spider enthusiast theorize that they’re Jumping spider mimics
Adult Dingy Cutworm Moths fly at night throughout summer and fall, resting and nectaring on flowers in the aster/daisy/composite family. DCM eggs are laid by late August on clovers, dock, members of the aster family, and a number of agricultural crops like alfalfa, tobacco, wheat and corn. Picture-Winged Flies, on the other hand, prefer their corn on the cob.
The Greater and the Lesser Grapevine Loopers (Eulithis gracilineata and E. diversilineata) live in suburban, rural, and wooded areas in eastern North America. Although the caterpillars are quite distinct, adults can be the very devil to differentiate;
Today we consider three fuzzy, fall caterpillars. Some long-haired caterpillars have irritating/poisonous hairs, but the sources that the BugLady consulted underplay the “toxicity card” in connection with these three. They all spend the winter as pupae. The BugLady didn’t find any mention of the adults’ feeding preferences, so they probably don’t feed at all.
The BugLady takes lots of pictures as she moseys around—flowers, landscapes, a surprising number of people, and, of course, all manner of bugs. Bug pictures may stall in the BugLady’s X–Files, awaiting identification—some for a long time. Here is a selection from the X–Files. In some cases the BugLady knows part of the story; in others, even less.
Duskywing and a Cloudywing Butterflies are sun-loving, chunky, hairy, small-sized, large-headed, often brown/brown-and-orange butterflies that are sometimes mistaken for moths. Like other butterflies, their antennae have club-shaped tips, but in most skippers the clubs have a tiny hook on the end.
