Vespa bicolor

Vespa bicolor, the black shield wasp, described by Johan Christian Fabricius in 1787, is a species of hornet which has been found to be the pollinator of an orchid,^[1] Dendrobium sinense (syn. Dendrobium christyanum), found only on the Chinese island of Hainan. Vespa bicolor also preys on honey bees, which it feeds to its larvae. The orchid produces a chemical that mimics a honey bee pheromone and attracts this predatory wasp.
