The bald-faced hornet is a wasp with a striking black and white body and a white face. It builds large, hanging paper nests in trees and bushes across North America. Its workers will defend the nest by stinging repeatedly, so it is important to keep well away from its nests.1

Nola ezagutu

Black and white colouring, unlike other yellowjackets of its genus, which are mostly black and yellow1
A white or "bald" face1
Three white stripes at the end of the body1
Adults average about 19 mm long, larger than other Dolichovespula species1
A large, egg-shaped, grey paper nest that hangs from trees or bushes, up to 58 cm long1

Askotan honekin nahasten da: Other Dolichovespula wasps are mostly black and yellow. The bald-faced hornet's black and white colouring and white face set it apart. It is not one of the true hornets, which belong to the genus Vespa.1

Datuak

It can spray venom from its stinger into the eyes of nest intruders, causing temporary blindness.1

Its colony can have 400 to 700 workers, the largest recorded colony size in its genus, Dolichovespula.1

Female bee moths can lay eggs in its nests, and the hatched larvae feed on the eggs, larvae and pupae inside, sometimes destroying large parts of the nest.1

Its nests are made from chewed wood fibres mixed with saliva, which dries into a papery structure.1

A colony lasts about 4 months in Washington, from mid-May to mid-September. Colonies in lower latitudes last longer.1
