Interactions between stoneflies and angiosperms are rarely documented, and most of them are poorly detailed. In this study, we describe the interactions between Obipteryx femoralis (Taeniopterygidae, Plecoptera) and Corylopsis gotoana (Hamamelidaceae). Field observations revealed that O. femoralis is a regular floral visitor of a small C. gotoana population. O. femoralis forages pollen directly from flowers with matured stamens, but does not forage nectar as other visitors. Pollen attachment in the samples was overall higher for female than males, especially for the head and mouthparts. Among the samples dissected after collection, only C. gotoana pollen was found in the gut contents of most females. In the ex-situ feeding experiment, most of the male and female samples showed preference for C. gotoana flowers with pollen to flowers lacking pollen, and had C. gotana pollen in their gut contents. The significant visits and pollen attachment indicate that O. femoralis flower visitors, particularly females, are potential pollinators of C. gotoana. Direct pollen foraging and constant pollen in the gut contents suggest that pollen feeding is important for the adult O. femoralis, at least females, and it might be related to egg production.
