Discussion. Vespa velutina has distinctive yellow tarsi and velvety appearing dark brown to black thorax and metasoma. It is native across Asia. However, V. velutina was introduced into Europe apparently with Chinese pottery in the past couple of decades (Keeling et al. 2017). Although this species preys on a variety of insects, including flies, dragonflies, and Orthoptera, it is a notorious predator of pollinators, particularly honeybees ( Apis mellifera and A. cerana). Apis cerana have adapted to this hornet using avoidance behaviors and balling behaviors where they heat the hornet to death (Abrol 2006).
