General Description
provided by University of Alberta Museums
Because of its relatively small size, this species could possibly be mistaken for a micro-moth. However, the comparatively large hindwing and a yellow forewing costa distinguishs this species.

Trophic Strategy
provided by University of Alberta Museums
Lichens growing on conifers, although development can occur on the conifer needles themselves (McGugan, 1958). Since this species also occurs in non-coniferous habitats, larvae must also feed on other lichens, possibly those associated with mature aspen and poplar trees.
