Hornet hornets may often be black and white. There is also a related genus of Asian nocturnal vespines, "Provespa", which are referred to as "night wasps" or "night hornets", though they are not true hornets. Some other large wasps are sometimes referred to as hornets, most notably the bald-faced hornet ("Dolichovespula maculata") found in North America. It is set apart by its black and ivory coloration. The name "hornet" is used for this and related species primarily because of their habit of making aerial nests (similar to the true hornets) rather than subterranean nests. Another example is the Australian hornet ("Abispa
Bald-faced hornet in different nests and workers in one colony might be as large as a queen in a different one. "D. maculata" create egg-shaped, paper nests up to in diameter and in length. Nests are layered hexagonal combs covered by a mottled gray paper envelope. Bald-faced Hornets create this paper envelope by collecting and chewing naturally occurring fibers. The wood fiber mixes with their saliva to become a pulpy substance that they can then form into place. The bald-faced hornet lives in North America, including Canada, the Rocky Mountains, the western coast of the United States, and most of the eastern
