Clodius
Butterfly.--The species may be distinguished from the following by the uniformly larger size and the more translucent outer margins of the fore wings in the male. Expanse, male, 2.50-2.75 inches; female, 2.50-3.00 inches.
Early Stages.--These await study. The egg and young larva were described by W. H. Edwards in the "Canadian Entomologist," vol. xi, p. 142, but we have no account of the later stages. The caterpillar feeds on Sedum and Saxifraga.
Clodius is found upon the mountains of California in spring and early summer. It is, like all its congeners, an alpine or boreal species.
