Abstract
This paper summarizes the life cycle and some aspects of natural history of the tropical pierid, Dismorphia virgo (Dismorphiinae) in Costa Rica. The precise taxonomic status of the butterfly in Central America has not been established, and it may represent a variable northern isolate of the common South American D. critomedia. Therefore, independent of whether the Central American form discussed in this paper has achieved full species status as the more northern virgo or is a subspecies or variety of critomedia evolving towards species status, this paper provides new information on the biology of the butterfly in Costa Rica. The establishment of precise taxonomic position awaits further study, and for the present purpose, I refer to the butterfly as D. virgo.
