Resumen:
The flesh fly community was surveyed on the shoreline of Río de la Plata at an ecological
reserve whose western border directly abuts downtown eastern Buenos Aires. Samples were taken at
monthly intervals from September 2004 to August 2005. To attract the flies, dog faeces and rotten cow
liver were used as bait. Overall number, species composition and sex ratio were referred to each chosen
bait. Of the thirteen species captured during the sampling period, Helicobia aurescens (Townsend),
Oxysarcodexia culmiforceps Dodge, Oxysarcodexia marina (Hall), Oxysarcodexia thornax (Walker),
Sarcophaga (Lipoptilocnema) koehleri (Blanchard), S. (L.) lanei (Townsend) and Tricharaea
(Sarcophagula) occidua (Fabricius) were recorded for the first time in Buenos Aires city. Regardless of
species composition, higher number of flies were obtained on faeces. Tricharaea (S.) occidua, was highly
dominant (78,35%) followed in abundance by Oxysarcodexia varia (7,82%), both species showing a
strong preference for dog faeces. Microcerella muehni and Oxysarcodexia paulistanensis did not show
any preference on either bait. Sex ratio was male biased for O. varia, while females were dominant for O.
paulistanensis and T. (S.) occidua, and no differences were found for M. muehni. Baits preference and
sex ratio could not be estimated for the remaining species due to their low abundance.
