Forest Yellowjacket (Vespula acadica)

Habits:

Forest yellowjackets are primarily found in heavily forested areas, with colonies lasting for one year.  Forest Yellowjackets are predators of only live prey, such as flies, caterpillars, hemipterans and aphids.

Nests:

Forest Yellowjackets typically build aerial nests, but subterranean nests in logs are not uncommon. This species usually has smaller colonies, with fewer than 500 workers.

Nature toward humans:

Because this species is primarily found in more heavily forested areas, the Forest Yellowjacket has limited contact with humans. If the nest is disturbed, Forest Yellowjackets will sting aggressively and persistently.
