DESCRIPTION: A large wasp, 20–30 mm long. The head is black with a yellow frons, a black thorax and a dark brown abdomen. Every abdominal segment has a narrow yellow trailing edge, with the exception of the fourth abdominal segment, which is entirely yellow-brown to orange. The upper legs are brown with yellow distal parts. In springtime, the females build cellulose nests, in which the queen lays her eggs. Asian hornet nests are large, egg-shaped structures which can measure 0.5 m or more in diameter. The nest entrance-hole is placed in the side of the nest. Only queens overwinter.

HABITAT: A range of natural habitats, farmland and urban areas. Nests are built in tall trees and on a variety of high objects.

STATUS: Present in several European countries.

SIMILAR SPECIES: The European hornet (Vespa crabro) is very similar, but is somewhat larger and has a yellow abdomen. The nest of European hornet has the entrance-hole on the underside rather than laterally.
