New Mexican Silver-spot

Argynnis cipris

Butterfly.--This species, which belongs to the Aphrodite-group, may be distinguished by the fact that the fore wings are relatively longer and narrower than in aphrodite. The black markings on the upper side of the wings in both sexes are narrower, the dusky clouding at the base of the wings is less pronounced, and the ground-color is brighter reddish-fulvous than in aphrodite. On the under side the fore wings lack in the male the pinkish shade at the base and on the inner margin which appears in aphrodite, and both the male and the female have the inner two thirds of the hind wings deep cinnamon-red, with only a very narrow buff submarginal band, deeply invaded on the side of the base by rays of the deeper brown color of the inner portion of the wing. Expanse, 2.75-3.15 inches. The insect flies from late June to the end of August.

Caterpillar, etc.--We know nothing of the larval stages of this insect. The specimens contained in the Edwards collection came from Colorado, Utah, and New Mexico, and these localities approximately represent the range of the species.
