用扫描电子显微镜观察了菠菜夜蛾3龄幼虫的表面超微结构。每个前气孔的乳头数为5-7个。腹部4-12段有腹缘。每个后螺旋盘有3条近乎直的裂隙，下缝和中缝比中缝和上缝靠得更近。虽然刺蜂的幼虫与泰国的另外两个近缘物种--水蝇(=Ophy ra)leucostoma(Wiedemann)和水蝇(=Ophy ra)siggaster(Wiedemann)相似，但一些形态特征有助于区分这两个物种，从而在法医调查中能够更准确地识别苍蝇幼虫。
The surface ultrastructure of third-instar larvae of Hydrotaea (= Ophyra) spinigera Stein was observed with scanning electron microscopy. The number of papillae in each anterior spiracle ranges from 5-7. Abdominal segments 4-12 possess ventral welts. Each posterior spiracular disc bears 3 nearly straight slits, with the lower and middle slits closer together than the middle and upper slits. Although the larvae of H. spinigera are generally similar to two other closely-related species in Thailand, Hydrotaea (= Ophyra) leucostoma (Wiedemann) and Hydrotaea (= Ophyra) chalcogaster (Wiedemann), some of the morphological features can help in differentiating these species, thus allowing more accurate identification of species of fly larvae in forensic investigation.
