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.
Underwing Moths can be seen in wooded areas from southern Canada and the Dakotas south to Texas, and thence east to the Atlantic. Adults fly during the second half of the moth season and hide by day in sheltered places. Adult Underwings feed on nectar or sap, and the BugLady sees them on the woodpeckers’ oranges at night. Their caterpillars are food specialists; most eat the leaves of willow, hickory, walnut, oak, locust, hawthorn, and poplar.
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
In lieu of the usual bug biography, the BugLady presents The Twelve Bugs of Christmas—a tribute to a dozen insects (a Baker’s Dozen, really) that were photographed this year but not featured in a BOTW. Let the singing commence.
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 has many pictures of bugs about whom she can’t find enough information to write a complete biography. Here are three more of them.
Baby bugs are not sweet and cuddly like, say, Golden Retriever puppies, but they have their own charm. Here are a few of the less-seen prairie babies.
Lichen Moths have it all! Toxins, aposematism, attitude, thoracic tympana and ultrasonic emanations, sensory setae, fecal flicking, mimicry, and even cannibalism! What an insect! LMs have some interesting sensory abilities, both as caterpillars and as adults. Like typical adult tiger moths, LMs have “ears” located on their thorax. They also make a variety of ultrasonic noises with organs on their thorax.
