A human cadaver is an attractive breeding habitat for necrophagous insects and for those species that are predators of necrophages. One of the important tasks of forensic entomologists is to provide a reliable list of species associated with decomposing bodies both in the adult and larval stages. We present here a case of a human cadaver discovered in Central Sweden and the insect fauna associated with it. This is the first report of Hydrotaea similis larvae developing in a dead human body. The larvae of H. similis have only recently been studied and, therefore, even if previously they had been collected during forensic casework or experiments, the larvae could not have been properly identified, except if reared to the adult stage. To facilitate future studies and casework, detailed descriptions are provided here of the morphology of third instar larvae of both H. dentipes and H. similis using combined SEM and light microscopy techniques. We describe characters that allow for easy species identification and discrimination of these two forensically important and closely related species.
人类尸体是食尸性昆虫以及食尸性昆虫捕食者的理想繁殖栖息地。法医昆虫学家的一项重要任务是提供一份可靠的与尸体分解相关的物种清单，包括成虫和幼虫阶段。我们在此呈现瑞典中部发现的一具人类尸体及其相关昆虫群落的案例。这是相似水蝇幼虫在人类尸体上发育的首次报告。相似水蝇的幼虫直到最近才被研究，因此，即使之前在法医案件工作或实验中收集到了它们，除非将其饲养至成虫阶段，否则幼虫也无法得到正确鉴定。为便于未来的研究和案件工作，本文使用扫描电子显微镜（SEM）和光学显微镜相结合的技术，对齿水蝇和相似水蝇三龄幼虫的形态进行了详细描述。我们描述了便于这两个对法医重要且密切相关的物种进行物种鉴定和区分的特征。
