Foregut contents of naiads of the damselfly species, Enallagma civile, collected from a permanent pond, were analyzed to determine the natural prey for immatures of this species. The analyses revealed the naiads containing prey had fed predominantly on chironomid larvae. Corixid, cladoceran, ostracod and aquatic mite remains were found in some of the naiad specimens examined. However, no remains of mosquito larvae were detected in any of the specimens, even though mosquito larvae were observed as being continuously present in the pond sites where the naiad specimens were collected.
对从一个永久性池塘采集的豆娘物种——普通细蟌稚虫的前肠内容物进行了分析，以确定该物种未成熟个体的天然猎物。分析显示，含有猎物的稚虫主要以摇蚊幼虫为食。在所检查的一些稚虫标本中发现了划蝽、枝角类动物、介形虫和水生螨的残骸。然而，在任何标本中都未检测到蚊幼虫的残骸，尽管在采集稚虫标本的池塘地点观察到蚊幼虫一直存在。
