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.
