Effect of melanism of alpine Colias nastes butterflies (Lepidoptera: Pieridae) on activity and predation
Abstract: Melanism in the Sulphur butterfly Colias nastes Boisduval was quantified and related to their ability to remain active under cool or cloudy conditions and to their risk of predation. Darker individuals were more active, moved greater distances, and disappeared from the population at a grea...
