Eastern yellowjacket
The eastern yellowjacket is a black and yellow wasp that lives in eastern North America. It builds paper nests, many of them underground, and lives in large family groups called colonies. People often meet it around recreational areas and buildings, and it can give a painful sting if its nest is threatened.1

- Black and yellow lines on the head, thorax and abdomen1
- Length of about 12.7 to 15.9 mm1

- Queens have one flared black line nearest the thorax, followed by thinner black lines, with two black dots between each line1

Its sting is painful. Wasps, bees, ants and sawflies (the order Hymenoptera) are the leading cause of anaphylaxis in humans, a severe allergic reaction. These reactions are usually triggered by proteins in the venom. Peptides called vespulakinins were first found in this species and are insecticidal, meaning they kill insects.1

When threatened, workers release an alarm pheromone that calls others to attack. Wasps near the nest entrance circle in a zigzag pattern and fly straight at the target.1

Fatgs
A large nest can have 10,000 to 15,000 cells, and about a third of them are queen cells.1
The nest envelope is made from chewed, decaying wood mixed with saliva, which makes it fragile.1
The species is a host for a social parasite, Vespula squamosa, which can take over its nests.1
Males gather in groups around prominent trees and bushes, where they patrol and wait for queens.1
Queens can mate with several males, and both queens and males can mate more than once.1
