Edwards' Fritillary

Argynnis edwardsi

Butterfly.--This beautiful insect is closely related to the Nevada Fritillary, from which it may be distinguished by the brighter color of the upper side, the heavier black borders, especially in the female sex, and the olive-brown color of the under side of the hind wings. The olivaceous of these wings greatly encroaches upon the marginal belt. Expanse, 3.00-3.25 inches.

Early Stages.--These have been carefully and minutely described by Edwards in the "Canadian Entomologist," vol.xx. p. 3. They are not unlike those of A. atlantis in many respects.

This species is not uncommon in Colorado and Montana.
