postman butterfly

or simply postman, is a brightly colored, geographically variable butterfly species found throughout Central and South America. The postman butterfly is predominately black with either red or yellow bands across the forewings. The postman butterfly has large long wings (35–39 mm). It is poisonous, and the red patterns on its wings are an example of aposematism.
