Nearly all of the winter moths to be seen
in November and December in the Greater Victoria area of Vancouver Island are
the abundant European Winter Moth Operophtera brumata. Miles outside
Victoria, however, in the surrounding countryside, the native North American
Bruce’s Winter Moth Operophtera bruceata is to be found, out-numbering
its European cousin. The two species are quite similar, but look for the black
Y-shaped or H-shaped mark in the middle of the forewing of bruceata.
