Like other Pieris species, the eggs are yellow and conical, with longitudinal ridges. Mature larvae are green with a pale dorsal stripe, and pupae range in colour from brown to green (Guppy & Shepard 2001). The first Cabbage Whites usually emerge in late April from hibernating pupae. There are usually three generations per year in Alberta (Bird et al. 1995). Up to four occur in southern BC, with development time of each generation varying from 4 to 8 weeks according to temperature (Guppy & Shepard 2001).
Conservation Not of concern. Diet Info
Larvae sometimes reach pest status on cultivated mustards such as cabbage, broccoli, cauliflower and canola. A large number of Brassicaceae have been recorded as hosts, particularly introduced, weedy species (Guppy &…
