Bald-faced Hornet Dolichovespula maculata (Linnaeus, 1763)  Synonyms: White-faced Hornet.

Status:

This large, striking wasp is actually a species of yellowjacket, despite the common name. It is very common throughout the state, and normally makes enclosed paper nests aerially in trees or bushes.

Description:

Dolichovespula maculata could potentially be confused with the blackjacket (Vespula consobrina) and the parasitic yellowjacket (Dolichovespula arctica). It can be distinguished from V. consobrina by a long oculomalar space (area between insertion of mandible and lower edge of eye), by showing a pronotal carina, and by less extensive pale markings on the abdomen. It can be distinguished from D. arctica by the black or almost entirely-black hind tibia (pale on arctica). D. maculata also tends to have less extensive pale markings on the abdomen, mostly restricted to tergite 4 onwards. (Buck et al. 2008)

Relationships:

Bald-faced Hornets build their nests using wood fiber from a variety of sources. Some songbirds use pieces of the hornets' paper-like nest in their own nest-building.

There are 92 records in the project database.
