The common name and the specific epithet refer to the white "St. Andrew's cross" on the hemelytra. There is a white arc at the base of the head. The scutellum is mostly red and the membrane is dark.
Dysdercus andreae is found in south Florida and on most islands of the West Indies.
In the West Indies this species develops on the seeds of the Portia tree (Thespesia populnea), a member of the mallow family that grows along the shoreline. The bugs can also develop on cotton, and in fact Dr. Harold Grau and his associates at Christopher Newport University have demonstrated that the species grows larger on cotton than on Thespesia populnea.
