| 本文概述了现生襀翅目稚虫的食性，其通常分为腐食-植食性、肉食性和杂食性；食性不同，其口器结构差异明显。古生物学家根据化石保存的口器结构，利用将今论古、形态功能分析等手段推测襀翅目化石稚虫的食性有腐食-植食性、刮食性、肉食性，以及因化石保存等因素导致的食性不确定。此外，选取热河昆虫群中襀翅目昆虫的优势种类Perlidae的一代表化石稚虫，对其保存的口器形态及其食性的关系进行了分析，推断其食性为捕食性。 |
| 英文摘要: |
| Feeding habits of extant Plecoptera nymph were briefly reviewed. Feeding habits of extant stonefly nymph were usually divided into detritivorous-herbivorous, carnivorous and omnivores; feeding habits was different, and its mouthparts structure was also different. According to the mouthparts structure that preserved in fossil stonefly nymph, paleontologists used the historical comparison, morphofunctional analysis methods and so on, speculated that the feeding habits of fossil nymphs were detritivorous-herbivorous, carnivorous, and unknown feeding because of the incomplete preservation. Moreover, one fossil Perlidae nymph was studied, which was the representative dominant species of fossil Plecoptera nymphs in Jehol Entomofauna, the character of mouthparts structure indicated it was carnivorous. |
