The entomoforensic investigation carried out on a decaying corpse found indoor has shown an unusual insect cenoses, that created some problems in estimating the actual time since death. Except for very few beetles, the body had been colonized by a monospecific population of the fly, Hydrotaea capensis Weidemann 1818 (Diptera, Muscidae), parasitized by two species of parasitoid wasps of the superfamily Chalcidoidae: Nasonia vitripennis (Walker, 1836) (Hymenoptera, Pteromalidae) and Tachinaephagus zealandicus Ashmead 1904 (Hymenoptera, Encyrtidae). The possible implications of the parasitoids on the fly population growth and density, the life cycle length, the maggots’ and pupae survival and their hindering the PMI evaluation and other entomologico-forensic inferences are discussed.
