| Summary: | Abstract In this contribution we examine the diversity, abundance and species richness of Calliphoridae in the Tijuca National Park, Rio de Janeiro, RJ. Specimens were collected monthly between September 2009 and August 2010, using sardines as bait, in three points: A, on the forest edge (22°56’846"S 43°17’496"W), B, 700m from it (22°57’073"S 43°17’832"W) and C, 1,200m into the forest (22°57’321"S 43°18’031"W), evaluating the indicator species at each point and the anthropogenic influences and abiotic factors that determine species distribution. A total of 16,364 Calliphoridae were collected and 17 species were identified. Species abundance was strongly positively correlated with temperature. The greatest number of flies was collected at A, but in this point, diversity was lower and most individuals collected belonged to the dominant species. Point C, conversely, had the lower abundance and the highest diversity. Chrysomya megacephala, an urban and synanthropic species, was dominant at point A, whereas Laneela nigripes and Mesembrinella peregrina, typically forest species, were considered indicators at points B and C, respectively, showing that the anthropogenic influence is more intense at the forest edge.
