Sleepy Orange

Synonym name is Abaeis nicippe. I don't know which name is the current acceptable name. I have seen Abaeis nicippe listed as the "standard name" with Eurema nicippe then noted as a synonym. The larger number of images appear when searching for Eurema nicippe so perhaps it is the current acceptable name. Another common name for this butterfly is nicippe sulfur.
