The larva is extremely variable in colour, ranging from green to yellow, orange brown or purple-brown; when feeding, larvae usually eat leaf tissue without cutting entirely through leaf (Wagner et al. 2001). The pupa overwinters, and adults come to light.
Conservation Not of concern Diet Info
Although the common name relates the fact that larvae feed on sweetfern (Comptonia) (Wagner et al. 2001), this plant does not occur in western Canada and larvae instead prefer alders (Alnus spp.) and birches (Betula
Although the common name relates the fact that larvae feed on sweetfern (Comptonia) (Wagner et al. 2001), this plant does not occur in western Canada and larvae instead prefer alders (Alnus spp.) and birches (Betula spp.) (Prentice 1963).
Range Newfoundland and Labrador west to the Yukon and coastal BC, south to GA in the East (McGuffin 1967, Wagner et al. 2001).
