The appearance of this moth signals the onset of late summer and early fall; the rich tan and rust notched wings resemble fall leaves. The larva is called the Maple Spanworm in the East, a poor name since it does not reflect the host preference over most of this species' range. The larvae are excellent twig mimics, complete with bumps resembling bud scars and mottled green and brown colouration. They are illutrated in color in Wagner et al. (2001). The eggs, which are laid in a row, overwinter, (Wagner et al. (2001). Larvae spin a cocoon among foliage rather than pupating in the ground.
Conservation
A common widespread species; no concern.
Diet Info
Larvae feed on deciduous trees and shrubs, particularly white birch (Betula papyrifera) and trembling aspen (Populus tremuloides) (Prentice 1963).
Range
Coastal BC east to Nova Scotia, south to GA, MO and south through the Pacific Northwest US (McGuffin 1987, Miller and Hammond 2000).
