The Black shield wasp (Vespa bicolor), described by Fabricius in 1787, is a species of hornet which has been found to be the pollinator of an orchid, Dendrobium sinense, found only on the Chinese island of Hainan. Vespa bicolor preys on honeybees, which it feeds to its larvae. Vespa bicolor is the most common species of large wasp in Hong Kong, along with members of the genus Parapolybia. It is found in a wide range of environments and can be found near human dwellings.
