The unique larva of this species, as the name suggests, has two tongue-like lobes along its back, unlike any other looper. In addition, the colouration and texture is bark-like, making it an excellent twig mimic (see Ives & Wong 1988 and Wagner et al. 2003). Pupation is in a loose cocoon among foliage. The pupa is very glossy, reflecting the colours of its surroundings. The nocturnal adults, emerging in late summer, resemble yellowing or wilted leaves. Eggs are laid on twigs and in old alder catkins, and overwinter (McGuffin 1987).
Conservation
Not of concern.
Diet Info
Larvae feed on deciduous shrubs and trees, such as alder, shrubby cinquefoil, currants, false azalea, blueberry, spiraea, willow and poplar (McGuffin 1987).
Range
Transcontinental in Canada, from coastal BC to Newfoundland, from southern YT and NT south to GA, MS and CA (McGuffin 1987, Wagner et al. 1997).
