摘要:蜻蜓目昆虫成虫陆生,稚虫水生，它们的分布和数量与水质有密切关系,可以作为水质监测的指示生物。其次蜻蜓为捕食性昆虫,它是天敌昆虫之一。在目前生物防治日益为人们所重视的情况下,对蜻蜓的生物学研究也就显得尤为重要。据统计国内系统地介绍蜻蜓生物学的专文很少。为了进一步探讨蜻蜓的生物学特性,本文作者首先对蜻蜓目中蟌作了总体的介绍，然后针对红腹细蟌（成虫尤其是稚虫）的形态学特征进行了详细的观察与描述，主要通过野外采集蜻蜓稚虫、饲养蜻蜓稚虫、拍照、照片处理、形态描述、文献检索、归纳、总结等方法完成。

Abstract: the Odonata adult terrestrial nymphs aquatic, their distribution and quantity and water quality is closely related can be used as water quality monitoring of the indicator organism. Followed by dragonflies predatory insects, it is one of the natural enemy insects. In the case of biological control increasingly the attention of biological research on dragonflies also particularly important. According to the statistics of domestic systematic introduction to a special article of dragonfly biology rarely.To further investigate the biological characteristics of the dragonfly, the author first Odonata Senegalensis made ​​a general introduction, and then for Ceriagrion latericium (especially nymphs) morphological features of the detailed observation and description, mainly through the fieldcollected dragonfly nymphs feeding dragonfly nymphs, camera, photo processing, morphological description, literature search, summarize, sum up the method to complete.
