The bluish appearance and rapid flight of this diurnal moth are vaguely reminiscent of Spring Azure butterflies (Celastrina lucia), which flies at the same time around cherry thickets. Larvae are rich emerald green with a row of yellow dorsal spots, and pupae overwinter (Wagner et al. 2001).
Conservation
Not of concern.
Diet Info
Larvae feed on cherries (Prunus) and hawthorns (Crataegus) (McGuffin 1981).
Range
Coastal BC east to Newfoundland, and from the Peace River region of BC and Alberta south to Oregon, Colorado and Georgia (McGuffin 1981, Wagner et al. 2001).
