Male great southern white of the orseis subspecies (Ascia monuste orseis) - a subspecies of butterfly - specimen, pressed inside of an almost flat, rectangular, plastic container. There is a raised "bubble" in the center of the plastic that houses the body of the specimen.

Original label identifies the specimen as "[Male] Pieris Orseis" - an outdated scientific name - and suggests that it was collected in São Paulo, Brazil.
