During recent years this species has been responsible for a considerable amount of defoliation in oak stands in Connecticut, New Jersey, and Pennsylvania. The pink-striped oakworm, Anisota virginiensis (Drury), oc- curs in southern Canada and throughout the eastern half of the United States. The larvae feed principally on various oaks, but also on many other hardwoods such as chestnut, hazel, maple, and birch. There are two generations per year in the southern parts of its (fig. 109) are brownish-red, often with a purplish cast. Females have a wingspread of about 37 mm. Males are considerably smaller. The forewings are thinner, less speckled, and more transparent beyond the discal dot than those of the orange-striped oakworm or the spiny oakworm. Full- grown larvae are about 50 mm. long. The body is greenish to brownish-yellow with two dorsolateral, rose-colored stripes and a similarly colored stripe along each side. Two spines on the second thoracic segment are slightly curved and are conspicu- ously longer than the others. The green-striped mapleworm, Anisota rubicunda (F.), is found throughout most of eastern United States and in adjacent areas of Canada. Its preferred hosts are maples, but it also feeds on various oaks and boxelder, especially where they are growing in mixture with maple. Populations may become heavy enough to cause serious defoliation anywhere within its range, but this is 301
