摘要：

We conducted a field survey and rearing experiment to investigate habitat, larval morphology, and ecology of Diplectrona aiensis Kobayashi, 1987. Larvae of this species look similar to those of D. takaii Nozaki, 2021, originally described as Diplectrona sp. DC by Akagi (1956); however, they can be distinguished by shape of the secondary setae on the head, thoracic nota, and abdominal segments. Our results revealed that generations of D. aiensis have overwintering and non-overwintering cohorts. Larvae build their retreat and capture nets on boulders and among leaf patches and prefer lower water velocity (mean: 22.2 m/s, range: 1.3 & LE; 52.4 m/s). Until the third instar, they feed only on detritus and after that, they feed on both animal and plant matter. This is the first study to report morphology, habitat, and ecology of D. aiensis.
