1. Relative abundance and its seasonal variation of Zygopteran larvae on Okinawajima Island
Members of the order Odonata are prevalent in both terrestrial and aquatic environments. Although morphological traits are well described in most of the species in Japan, there is little information on larval ecology of these species especially in Ryukyu Islands. We investigated the larval assemblage of damselflies (Suborder Zygoptera) in two ponds on Okinawajima Island, Japan, for 13 months. In total, four species were found in one of the ponds (Ogimi) and three in the other (Kunigami). Among these, Paracercion melanotum (Selys) dominated the assemblages, accounting for up to 71% of the total abundance in both ponds. Based on the best model selected by AIC, we found that the relative frequency of the larvae varied among damselfly species, seasons, and macrophyte species of habitats. Moreover, patterns of seasonal changes and habitat selection in respect to macrophyte species also varied among damselfly species..
