The Panoquina errans maintains physical attributes that display dimorphism. For instance, male southern checkered skippers have complete checks in the wing fringe and a blue-gray upper side. In contrast, female butterflies have a black upper side on the wings. Both males and females display large white spots which form median bands across both wings. While both sexes have relatively distinct physical characteristics, positive identification can be made only through dissection and observation of the male genitalia. The wing-span of the Panoquina errans can range from 2.5-3.8 cm. The general habitat of the southern checkered skipper includes open, sunny areas with short vegetation and some bare soil. The geographic distribution includes low altitude regions including southern California, southern Arizona, southern New Mexico, Florida and Mexico (1).
