Extract

From 1981 to 1984, a “looper” complex was responsible for the defoliation of approximately 648 000 ha of hardwood forests in several counties of eastern West Virginia. The complex consisted primarily of four species of Geometridae (Lepidoptera) with larval composition at three study sites in 1983 ranging from 77 to 94% for the half-wing geometer, Phigalia titea (Cramer); 2-13% for the linden looper, Erannis tiliaria (Harris); 8% for Phigalia strigataria (Minot); and 1–2% for the fall cankerworm, Alsophila pometaria (Harris) (Butler 1985a, 1985b, 1986).
