Extract
Larvae of the mourning cloak butterfly, Nymphalis antiopa (L.), are gregarious feeders occumng most commonly on Salix spp. (willows), Ulmus spp. (elms), Populus spp. (poplars), and Betula spp. (birches), but occasionally on other trees and shrubs (McGugan 1958; Tietz 1972; Howe 1975). They frequently cause noticeable defoliation of ornamental elms; hence the common name, spiny elm caterpillar (Rose and Lindquist 1982).
