Nemoura nankinensis and R. vespertilio were the only two stonefly species collected during our trip at Mt. Maoshan. Larvae of N. nankinensis inhabited leaf packs and also undersides of small stones ( Fig. 11A ). The newly emerged male adults, typical of many nemourids, could be found on top of dry rocks ( Fig. 11 B–D). Apparently, males drummed by bending the abdomen and tapping rock surfaces ( Fig. 11 E–F). Adults and larvae of N. nankinensis were collected along most sections of the mainstream flowing from the peak of the mountain into the valley. This species occurred from rapid-flowing sections of the stream to areas where the stream became subterranean. Several adults were found even along a valley section with no flow and much submerged filamentous algae and macrophytes. Several years ago, this section of the stream was a fast flowing ( Fig. 11 G–H). FIGURE 11. Nemoura nankinensis Wu, 1926 .
