摘要:
An interesting and unusual instance of swarm‐feeding was observed when large numbers of the damselfly,Hetaerina americanafed on hatches of mayfly subimagos over riffle areas of the White River in Indiana. The phenomenon of swarm‐feeding in Odonata is reviewed and delineated and the behavior observed forH. americanadiffers considerably from previously observed patterns.
