Abstract
The species diversity and population of dragonfly larvae are spatially different. In this study, we did mesocosm experiments to examine the effect of litter supply on the dragonfly larvae community. Size and species composition of dragonfly larvae and presence / absence of chironomid, a food resource for dragonfly larvae, were also controlled in the experiment. The results indicated that the litter provide the hiding places for small larvae, and consequently extend the survival time of them. Therefore, the litter supply regulates the structure of the dragonfly larva community.
