There are two subspecies of this moth in NA. The host plant of E. semipurpurella pacifica is Holodiscus discolor (Oceanspray) - a species not found, in Canada, east of BC.(?)
Because this specimen was collected in northern NS - and its host plant is Betula (Birch) - it must be the other subspecies E. semipurpurella semipurpurella.
