Temperature Induced Seasonal Melanism in the Wings of Copaeodes Minima (Lepidoptera: Hesperiidae)

  • James E. Lewis

Abstract

The effects of photoperiod and temperature on wing coloration in the skipper Copaeodes minima (Hesperiidae) was studied in the laboratory. Individuals reared in incubators at 20 @*C had a higher proportion of darkened scales along a transect on the dorsal surface of the secondary wings than individuals reared at 30 @*C. Photoperiod (10h vs. 16h light) did not affect patterns of scale coloration.
