Abstract
Many ant species play a relevant role in the successional patterns of insects colonizing human and animal corpses. Although feeding behavior in ants depends on the trophic preferences of each taxon, these insects are often reported in several studies as predators of eggs, larvae, and adults of necrophagous insects. Among ants, some species are known to cause damage on human and animal dermis, known as post-mortem skin artifacts. The extensive activity of worker ants on corpses may hinder forensic pathological investigations aimed at determining the cause and location of death, as well as the assessment of entomologists in estimating the minimum post-mortem interval. We report for the first time a case of skin lesions on a human corpse found in a suburban area of the city of Cosenza (Calabria, Southern Italy), caused by the ant Pheidole pallidula (Hymenoptera: Formicidae). During the autopsy, numerous individuals (major and minor workers) were observed feeding on the corpse, but no other insects were found on it. We discuss the appearance of skin artifacts caused by P. pallidula and provide an overview of the genus Pheidole in forensic entomology.
