About the Sleepy Orange

Eurema nicippe, the sleepy orange, is a North American butterfly in the family Pieridae. Its range spans from Central America to north along the United States–Mexico border, and it often travels further to non-mountainous regions of the Southeastern United States.

This species occupies a wide range of habitats in open and disturbed environments such as roadsides, agricultural land, and scrub habitats. In addition to its broad distribution, E. nicippe displays complex behavioral and ecological interactions such as host plant specialization and oviposition decision making based on both visual and chemical cues.

The sleepy orange is a bright orange butterfly with the upperside of the wings having wide black borders. The forewing costal margin has a small, narrow black marking that resembles a closed eye. Contrary to popular belief, its name originates from this wing patterning, rather than its behavior; the butterfly has a very rapid flight pattern when disturbed. The underside of the wings varies seasonally: summer forms are bright yellow with brick-red markings, while winter forms are browner and more heavily marked. It has a wingspan of 13⁄8–21⁄4 inches (35–50 mm... Wikipedia →
