Protophormia terraenoenopsis（Robineau‐Desvoidy）（双翅目：丽蝇科）和Phormia regina（Meigen）（双翅目：丽蝇科）是形态相似的苍蝇物种，常用于估计死后时间。成虫的野外采集和储存可导致颜色变化，特别是在帽状花序和须上;通常采集的标本显示出翅膀磨损或真菌生长等损伤。我们使用照片（ImageJ版本1.49）测量额宽：总头宽比，以区分这两个物种。两性的种间差异最大的是雄性：12.34%的土生梭子蟹对1.62%的里脊梭子蟹，雌性：40.25%的土生梭子蟹对33.65%的里脊梭子蟹。将此功能扩展到未来的吹飞键中将有助于在其他功能被阻挡时区分现场捕获的标本。
Protophormia terraenovae (Robineau‐Desvoidy) (Diptera: Calliphoridae) and Phormia regina (Meigen) (Diptera: Calliphoridae) are morphologically similar blow fly species commonly used for estimating postmortem intervals. Field collection and storage of adults can result in color changes, in particular on calypters and palps; often collected specimens show damage such as wing fray or fungal growth. We measured the frons width: total head width ratio using photographs (ImageJ version 1.49) to differentiate these two species. Both sexes were distinguishable to species, with the greatest difference between males: 12.34% P. terraenovae versus 1.62% P. regina, less so for females: 40.25% P. terraenovae, versus 33.65% P. regina. Incorporating this feature into future blow fly keys would help with distinguishing field‐caught specimens when other features are obstructed.
