North American Ecology (US and Canada)
provided by North American Butterfly Knowledge Network
Resident in northern North America and intermountain West (Scott 1986). Habitats are WILLOW BOGS. Host plants are usually shrubs with hosts restricted to a few species mostly in one genus (SALIX) of family SALICACEAE. Eggs are laid on the host plant singly. Individuals overwinter as 2nd, 3rd or 4th instar larvae. There is one flight each year with the approximate flight time JUN15-JUL15 (Scott 1986). Sometimes listed as a subspecies of Colias scudderi (Scott 1986).

General Description
provided by University of Alberta Museums
Most similar to the Pink-edged Sulphur (C. interior), but gigantea is larger (forewing length 26 - 32 mm, compared to 22 - 27 mm), with a larger discal spot and often with a more pronounced satellite spot. The shape of the forewing is also more rounded. Boreal region populations are subspecies mayi, while those from the Crowsnest Pass region southward are slightly smaller and are considered supspecies harroweri (Bird et al. 1995).

Life Cycle
provided by University of Alberta Museums
The immature stages are undescribed. It is believed that larvae overwinter (Bird et al. 1995). The wet, shrubby areas inhabited by this species means it is not often observed, but road allowances through fens and bogs with regenerating willows are good places to look for this insect.

Trophic Strategy

The larvae feed on willows (Layberry et al. 1998). There are no published reports of adult feeding behaviour.
