The eggs are smooth, green and round, laid singly on the host plant (Pyle 2002). Mature larvae are velvety green with a pair of yellow-rimmed eyespots and a yellow stripe on the mid-thoracic segment (Pyle 2002). The tan and brown-streaked pupa overwinters (Pyle 2002). This species tends to have an extended emergence period and a longer lifespan than smaller species (Pyle 2002).
Conservation
Not of concern.
Diet Info
The Adults are avid flower visitors and males often mud-puddle (Guppy & Shepard 2001). Larvae feed on a variety of shrubs in B.C., including alder, apple, birch, cherry, poplar and willows (Guppy & Shepard 2001).
Range
Ranges from southern BC south throughout the western US (Opler 1999). The first confirmed Alberta specimen of this species was collected by Ted Pike in the Castle River region in 2002 (B.C. Schmidt, unpubl. data).
