Finned-willow Prominent Moth

Identification

Adults

Notodonta scitipennis is a predominantly eastern North American moth that barely enters northeastern British Columbia. It is a medium-sized to large moth (17–20 mm) with a gray and orange-brown forewing that has a flange along the posterior margin.  It resembles closely Notodonta pacifica in color and pattern.  In general, the forewing of N. scitipennis is smoother gray with less whitish gray in the anterior median area, the brown areas on the forewing are warmer colored with more orange, and the hindwing veins are lighter gray.

This species and N. pacifica are best separated by locality.  Notodonta scitipennis occurs only in northeastern British Columbia while N. pacifica flies from southern British Columbia to California.
