Major Yellowjacket and Hornet Species in North America

Species Common Name Distribution Habitsb
Dolichovespula arenaria aerial yellowjacket transcontinental does not ordinarily scavenge for protein, but in late summer may be attracted to sweets.
D. maculata baldfaced hornet transcontinental predator and occasional scavenger; not as sensitive to nest disturbance; not a pest unless colony located close to human activity
Vespa crabro germana European hornet forested areas of eastern North America; native to Europe predator; sometimes girdles branches and twigs of trees and shrubs; primarily a forest species, so has less contact with people and is therefore less of a stinging hazard
Vespula acadica forest yellowjacket forested areas of Canada, Great Lakes states, much of western U.S., & Alaska strict predator; primarily a forest species so less contact with humans, but can be quite aggressive when nest is disturbed
V. atropilosa prairie yellowjacket prairies and open forest areas of much of western U.S. & Canada strict predator; nests in yards, golf courses, pastures, etc., and can also nest in walls; usually not a problem unless nest is disturbed
V. consobrina blackjacket forested areas of Canada, northern U.S. strict predator; primarily a forest species so less contact with humans, but can be aggressive when nest is disturbed
V. germanica German yellowjacket transcontinental; native to Europe predator and scavenger; nests mainly in structures, but can nest in the ground or in trees; colonies can be perennial; exploits a variety of food sources, so is usually a pest; can be aggressive when nest is disturbed
V. maculifrons eastern yellowjacket eastern & central U.S. to the Mountain Region predator and scavenger; nests in yards, golf courses, recreational areas, and buildings; is the primary pest yellowjacket where it occurs
V. pensylvanica western yellowjacket western North America and Hawaii predator and scavenger; scavenges extensively for protein, especially later in the year; nests mainly in ground, but also in buildings; primary pest yellowjacket where it occurs; can be aggressive when nest is disturbed
V. squamosa southern yellowjacket eastern, southeastern U.S. to Central America predator and scavenger; parasitic on V. maculifrons; will scavenge for protein; nests mainly in the ground in disturbed areas, but also in buildings; perennial colonies possible in subtropical locations; can be aggressive when nest is disturbed
V. vidua none eastern U.S. predator; nests mainly in the ground in disturbed areas but also forests, sometimes in buildings; not a stinging hazard unless nest is located where it can be disturbed by human activity
V. vulgaris common yellowjacket transcontinental, Hawaii; prevalent in heavily forested areas in the West predator and notorious scavenger of nearly any protein or sugar source; nests mainly in the ground, but also in buildings; colonies can be very large

a From Akre et al., 1981.

b Those species that are scavengers are more likely to be pests around garbage cans and where food is eaten outside.
