This paper aimed to study the diversity of dipterans of the families Calliphoridae, Fanniidae, Muscidae and Sarcophagidae in a fragment of the Atlantic rainforest located in the Ilha do Governador, Rio de Janeiro State, Brazil, from July 2001 to July 2002. The temporal variation occurrence of the most frequent species of the studied families in the fragment was also analyzed. The collections were performed with traps using baits of rotten fish. The most frequent and most constant species was Chrysomya megacephala (Fabricius, 1794) which is exotic and was introduced about twenty years ago in the American Continent.
