For the purpose of accuracy enhancement in estimating postmortem interval during the warm/cold migratory season, piglet carcasses covered with clothes were placed outdoors within a residential area to observe the colonizing insect fauna and the decomposition process. The first colonizer, green bottle fly Lucilia sericata, oviposited within 20 hours after the piglet carcasses were placed. Four coleopteran species and 5 dipteran species were recovered from the piglet carcasses. The rove beetle, Creophilus maxillosus, was the sole predator for the dipteran larvae and the maggot mass made inroads into the soft tissue of piglet remains in approximately 7 days. The first colonizers of the warm/cold migratory season were two blowfly species, Calliphora lata and Triceratopyga calliphoroides. Although sarcosaprophagous insect fauna and the decomposition process of piglet carcasses were similar in late autumn and early spring, some differences were noticed according to whether or not dipteran pupae, puparia, and coleopteran activities were observed.

为了提高在暖/冷迁徙季节估计死后时间间隔的准确性，将猪尸体盖上衣服放置在居民区户外，观察昆虫的定植区系和分解过程。第一个殖民者，绿瓶蝇丝光露蝇，在仔猪尸体放置后20小时内产卵。从仔猪尸体中检出4种鞘翅目动物和5种双翅目动物。双翅目幼虫的唯一捕食者是棘甲虫（Creophilus maxillosus），蛆团在大约7天内侵入仔猪遗体的软组织。暖/冷迁徙季节的第一批殖民者是两种吹蝇，Calliphora lata和Triceratopyga calliphorides。虽然深秋和早春期间食肉昆虫区系和仔猪尸体分解过程相似，但根据是否有双翅目蛹、蛹和鞘翅目活动的不同，发现了一些差异。
