Cephrenes acalle

Cephrenes acalle, commonly known as the plain palm dart,^[2] is a butterfly belonging to the family Hesperiidae.^[3] An examination of the type specimen showed that it was identical to Cephrenes chrysozona lompa Evans 1934 based on genitalia. This has led to Cephrenes chrysozona being treated as a synonym. The species breeds on palms including coconut, Calamus, Elaeis, Roystonea and Prychosperma.^[4][5]
