Abstract

In order to estimate mating frequencies of females, spermatophores stored in the bursa copulatrix were examined in three Asian species of the genus Lepidostoma Rambur (Lepidostomatidae): L. complicatum (Kobayashi 1968), L. satoi (Kobayashi 1968), and L. itoae (Kumanski & Weaver 1992), during their flight seasons of 2011 to 2016. In all three species, several spermatophores were detected, particularly in late seasons, suggesting that multiple mating occurs in these caddisflies.
