许多齿科物种的幼虫通常出现在同一淡水生态系统中。然而，不同种类的幼虫之间是否存在食物分离仍然是未知的。在这项研究中，我们在日本京都三郎池浮垫的各个地点收集了不同季节不同种类的齿幼虫，并检查了优势物种的丰度和肠道内容物。我们的分析表明，生境和季节性丰度的牙形幼虫没有显着重叠之间的大多数对的优势种。此外，食物重叠的程度是不相关的幼虫生物量在微生境。这些结果表明，虽然幼虫的食物习惯是相似的物种之间，浮垫上的各种植被类型的存在允许许多odonate物种栖息Mizorogaike池。
Larvae of many odonate species commonly appear within the same freshwater ecosystem. However, it remains unknown whether there is a dietary separation among the larvae of different species. In this study, we collected different species of odonate larvae in different seasons at various sites on the floating mat of Mizorogaike Pond in Kyoto, Japan, and examined the abundance and gut contents of the dominant species. Our analyses showed that habitat and seasonal abundance of the odonate larvae did not significantly overlap between most pairs of the dominant species. Moreover, the degree of dietary overlap was not related to larval biomass in microhabitats. These results suggest that, although larval food habits were similar among species, the existence of various vegetation types on the floating mat allowed many odonate species to inhabit Mizorogaike Pond.
