A decomposition study conducted with a piglet ( Sus scrofa L) carcass was used to determine Diptera sarcosaprophagous community structure, dynamics and the succession patterns during the end of spring and summer in Coimbra, Portugal. A modifed Schoenly trap was used to collect the arthropod fauna, in a sun exposed environment. Five decomposition stages were identifed and 12,042 adult Diptera, corresponding to 66 species, were collected and identifed. Calliphoridae represented 52% of the total amount of Diptera collected, followed by Muscidae with 27.8%, Fanniidae with 4.7% and Sarcophagidae with 3.5%. Calliphora vicina, C vomitoria, C albiceps, L caesar and H ignava were the most abundant species. The distribution of taxa in each decomposition stage is shown, and comparisons with other studies from the same biogeographical area, the Iberian Peninsula, are made. Changes in Diptera community composition along decomposition process, as well as decomposition stages, are statistically supported. The information given is the first ecological study about the sarcosaprophagous Diptera community present in Portugal. It enhances the biological knowledge on this fauna and will be very useful to begin a database indispensable to forensic practise.
