Extract

The winter moth, Operophtera brumata (Linn.), was not known to occur in North America until 1949, when it was first reported from the south shore of Nova Scotia by Hawholdt and Cuming (2) and Smith (4). By that time this introduced species was well established. It is suspected that the winter moth in association with the fall cankerworm, Alsophila pometaria (Harr.), has been causing considerable defoliation of deciduous tree species in the region since the early 1930's (2). The habits and stages of the winter moth have been described briefly by Smith (S), who also has indicated the important differences between the winter moth and the fall cankerworm (4).
