The sarcosaprophagous fauna plays a key role in organic matter decomposition. Moreover, the biological,ecological and behavioral specificities of the taxa are useful to reconstruct the decay history of a corpse orcarcass, often back to the lethal event. Here we report the seasonal succession of the insect fauna on a pigcarcass exposed in a rural area in Calabria (southern Italy) during summer 2007 and 2008. The aim is toidentify and qualitatively assess the major taxa of forensic importance in this region. The principal flyinvaders were Lucilia caesar (L.), L. sericata (Meigen, 1826), Chrysomya albiceps (Wiedemann, 1819),Sarcophaga (Meigen, 1826) spp. and Amobia (Robineau-Desvoidy, 1830) spp., Musca domestica (L.) andMuscina stabulans (Fallen, 1817). The primary beetle species collected in summer belonged to Dermestidae,Dermestes maculatus (De Geer, 1774) and Cleridae, Necrobia rufipes (De Geer, 1775). This paper alsoexamined the ecological role of ants in the insect succession and describes the evidence of skin injuriesdirectly inflicted by the acrobat ant Crematogaster (Acrocoelia) scutellaris (Olivier, 1791) (HymenopteraFormicidae) while feeding on pig carrion. Ants belonging to two other species were also collected: Camponotusaethiops (Latreille, 1798) and Tetramorium semilaeve (André, 1881). Ants can invade carcasses andcorpses directly, disrupting blowfly egg laying or preying on their larvae. Our data on the carrion faunalcomposition and role of ants as invaders should be useful for further forensic cases in Calabria (southernItaly). This is among the few reports of ants as forensically relevant species.
