Several traces may reveal the post-mortem relocation of a corpse. Insects are particularly useful for that purpose. The use of insects for inferring the transfer of a corpse rests on a premise that particular species colonise corpses in different habitats. However, only some insects reveal a strong preference for a given type of habitat. In order to find those insects which colonise corpses exclusively in open habitats, as opposed to forest habitats, a pig carrion study was made in rural open and rural forest habitats of Central Europe. Lucilia sericata (Diptera: Calliphoridae), Dermestes frischi, Dermestes laniarius (Coleoptera: Dermestidae), Omosita colon, some species of Nitidula (Coleoptera: Nitidulidae) and Necrobia rufipes (Coleoptera: Cleridae) were found to breed exclusively in open habitats. Only Oiceoptoma thoracicum (Coleoptera: Silphidae) avoided definitely breeding in open habitats. Sarcophaga caerulescens (Diptera: Sarcophagidae) regularly bred in open habitats but rarely bred in forests. Accordingly, L. sericata, D. frischi, O. colon, species of Nitidula and supposedly N. rufipes may be classified as indicators of corpse relocation from rural open to rural forest habitats of Central Europe. Only O. thoracicum may be classified as an indicator of the relocation in an opposite direction.
有几处痕迹可能表明尸体被转移。昆虫在这方面特别有用。利用昆虫推断尸体的转移是基于一个前提，即特定物种会在不同的栖息地中寄生尸体。然而，只有一些昆虫对特定类型的栖息地表现出强烈的偏好。为了找到那些只在开阔栖息地而不是森林栖息地中寄生尸体的昆虫，在中欧的农村开阔和农村森林栖息地进行了猪尸研究。发现丽蝇（双翅目：丽蝇科）、食尸甲（鞘翅目：皮蠹科）、毛食尸甲（鞘翅目：皮蠹科）、奥莫西塔粪金龟（鞘翅目：粪金龟科）、某些尼图拉甲虫（鞘翅目：金花虫科）和红足皮蠹（鞘翅目：拟步甲科）专性地在开阔栖息地中繁殖。只有 Oiceoptoma thoracicum（鞘翅目：埋葬甲科）绝对避免在开阔栖息地中繁殖。蓝丽蝇（双翅目：丽蝇科）定期在开阔栖息地繁殖，但很少在森林中繁殖。因此，丽蝇、食尸甲、奥莫西塔粪金龟、尼图拉甲虫和可能的红足皮蠹可被归类为从中欧农村开阔栖息地到农村森林栖息地的尸体转移指示生物。只有 O. thoracicum 可被归类为向相反方向迁移的指示生物。
