Dormant bald-faced hornet nest taken from tree.

Bald-faced hornet. Also called white-faced hornet. Bald, in this case, may refer to the white face rather than an absense of setae or hair that is profuse on the rest of the body.
Bald-faced hornet—Dolichovespula maculata. Food: insects, expecially various flies. Considered beneficial though the hornets will attack those too close to the nest.
Only the queen survives the winter. She builds a small nest and produces sterile females who take over all the work of building the main nest and rearing the young. The nest consists of several tiers of combs with an outside covering and entrance hole. The nest is used only for one season, and it is safe to remove it during the winter.
