scientific name    Odontosia elegans    

common name     Elegant Prominent

Mature poplar forest and mixedwood forest with poplars.

Adults in Alberta late May through mid-July, larvae from late June through September.

A rather large (4.5-6 cm. wingspan) moth with dark slate-grey forewings, shading to paler gray toward the lower margin . The forewing margin is somewhat scalloped, with a short, white basal line with pale orange scaling below and a prominent "tooth" midway along the lower margin. The hindwing is white, shading to dark grey in the anal angle. Unmistakable.

life history
The adults are nocturnal and come to light. There is a single brood, and the larvae are solitary defoliators. They overwinter in the pupal stage.

A widespread and fairly common species; no concerns.

diet info
No Alberta data available; elsewhere poplars. Canadian records (Prentice et al. 1962) are all from aspen poplar (Populus tremuloides).

Transcontinental across southern Canada, in particular in the parkland and southern boreal forest region, south to Texas. In Alberta found across the aspen parklands and the foothills, north into the boreal forest at least to the Ft. McMurray area.
