or October, they crawl to the ground and often do considerable 
wandering in search of suitable places to pupate. Pupation takes 
place in the soil at a depth of 3 to 4 inches. There is one and 
possibly two generations per year, depending on location. 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 range.Adults (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
