Common Name: Io moth
Scientific Name: Automeris io
Season: Usually two generations in the Northeast.
Food: Feeds on many different trees, shrubs, legumes, and grasses (this one was feeding on black locust).
Ecology: Adults emerge during late morning or early afternoon, and mating takes place in the late evening. Females lay clumps of eggs on leaves or stems of the host plants. Young caterpillars feed together as a group and move in long “trains” while older caterpillars feed alone. Papery cocoons are spun in litter under the host plant or in crevices.
