In the case of unidentified bodies the estimation of the period since death or of the season of death plays an important role to focus the attention on a reduced number of people among the ones reported missing. Forensic entomology can be one of the most important methods for these estimations, as occurred in this case. Flies are typically the first insects to colonize a dead body. The case reported here concerns the colonisation by insects of a male body in advanced decay found during the winter in Central Italy. This case is of particular interest as few data are available on the entomological evidence in the cold season. In particular, in this case we recovered Calliphora loewi (Calliphoridae), a species never collected before on dead bodies in Southern Europe. Larvae of the black soldier fly Hermetia illucens (Stratiomyidae), pupae and larvae belonging to genus Hydrothea (Muscidae), and Necrobia rufipes (Cleridae) specimens were also collected. The estimated PMI enabled identification of the cadaver, confirmed by DNA analysis.
在身份不明的尸体情况下，对死亡时间或死亡季节的估计对于将注意力集中在报告失踪的人数上起着重要作用。法医昆虫学可以是这些估计中最重要的方法之一，就像在这种情况下一样。苍蝇通常是第一个在尸体上繁殖的昆虫。本报告涉及到在意大利中部冬季发现的一具高度腐烂的男性尸体被昆虫定殖的情况。由于有关寒冷季节昆虫学证据的数据很少，因此这个案例特别有趣。特别是，在这种情况下，我们采集到了从未在南欧尸体上采集过的丽蝇科丽蝇属（Calliphora loewi）。还采集了黑蝇属（Hermetia illucens）幼虫、蛹和幼虫、水蝇属（Hydrothea）（蝇科）和黑肩绿蝇属（Necrobia rufipes）（皮蠹科）标本。估计的 PMI 有助于通过 DNA 分析确认尸体身份。
