Ecological studies of the cyclorrhaphous flies under urban and suburban environments in Tokyo and a neighbouring city

Abstract

Community structure and ecological distribution of flies (Diptera, Cyclorrhapha) attracted to putrid flesh traps in the urban and suburban areas in Tokyo were studied from January 1990 to November 1992. Trapping sites were classified into eight types, and 179 species of flies belonging to twenty four families were collected. The trapping site similarities were clustered by Pianka's α index. Composition rate of 47 dominant species in each trapping site was analyzed.
