Blowflies utilize discrete and ephemeral breeding sites for larval nutrition. After the exhaustion of food, larvae begin dispersing in search of sites to pupate or additional food sources, a process referred as postfeeding larval dispersal. Some of the most important aspects of this process were investigated in the blowfly Chrysomya albiceps, employing a circular arena to allow radial dispersion of larvae from the center. The results showed a positive correlation between burial depth and distance, and a negative correlation between distance and pupal weight. These results can be used in forensic entomology for the postmortem interval estimation of human corpses in medico-criminal investigations.
丽蝇利用离散且短暂的繁殖场所获取幼虫营养。食物耗尽后，幼虫开始分散，寻找化蛹地点或其他食物来源，这一过程被称为摄食后幼虫扩散。在白纹伊蚊中对这一过程的一些最重要方面进行了研究，采用圆形场地以使幼虫从中心呈放射状扩散。结果表明掩埋深度与距离呈正相关，距离与蛹重呈负相关。这些结果可用于法医昆虫学，在法医调查中估计人类尸体的死后间隔时间。
