About Polygonia progne (Cramer, 1775)
This species has a wingspan ranging from 4.4 to 6.3 cm. The upper surface of the wings is bright orange-brown; summer forms of the species often have a dark border along the hindwing. Both winter and summer forms have only a small number of yellow spots on their wing borders. The underside of the wings is charcoal gray, and bears L-shaped silver markings. This species is most commonly encountered near dirt roads and stream beds, and it generally occupies hilly terrain or canyon lands. Adults of this species fly twice per year: once between April and May, and again between June and August. Adults mate and lay eggs during the first annual flight. These eggs hatch to produce the summer generation. Eggs laid by the summer generation hatch in October, and the resulting individuals enter hibernation.
