蝇蛹是蝇类生活史中的一个重要环节,对蝇蛹的形态研究有助于蝇类的形态分类。本文报告丽蝇科常见四种蝇蛹(叉丽蝇,红头丽蝇,丝光绿蝇、大头金蝇)的形态特征,为蝇蛹的分类提供资料。观察结果表明:不同蝇种其蛹的形态也不相同,蝇蛹的形态可以作为蝇类分类的一条途径。 Fly pupae is an important link in the life history of flies, and the study on the morphology of fly pupae is helpful for the morphological classification of flies. In this paper, the morphological characteristics of four common fly pupae (Fork, Fly, Lucilia sericata, Kingfly) were reported in this paper to provide information on the classification of fly pupae. The observation shows that the morphology of pupae of different fly species is also different, and the morphology of pupae can be used as a way to classify flies.
