Plecopteran ecology has been scarcely studied, and interactions between adult plecopterans and flowering plants have been rarely reported. Here we report the pollination behavior of a Plecoptera species, Strophopteryx nohirae (Plecoptera, Taeniopterygidae), and its relationship with Corylopsis gotoana (Hamamelidaceae). The flowers were visited mainly by dipterans and hymenopterans. S. nohirae visits were not as common, but were constant during the observations. Males and females of S. nohirae were observed to forage on pollen. The females were frequently found resting, while the males were more active and appeared to be searching for mates. Pollen tube observation under UV radiation showed that female S. nohirae contributes to the pollination of C. gotoana.
