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

Como recoñecelo
- Black and yellow lines on the head, thorax and abdomen1
- Length of about 12.7 to 15.9 mm1
- Spots on the head, which give the species its scientific name1
- Queens have one flared black line nearest the thorax, followed by thinner black lines, with two black dots between each line1
Adoita confundirse con: It can be told apart from other wasp species by its smaller size and its abdominal pattern. Other yellowjacket species are also black and yellow, and in most areas where it lives, this is the most common yellowjacket species.1
Poder da pezoña
A pezoña sae por un ferrete.
Que fai a súa pezoña?
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
Que perigoso é para as persoas?
Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.It is known to inflict painful stings and defends its nest aggressively. Its nests are often treated as a pest because they are found so often in recreational and residential areas.1
Que fai cando ten medo?
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
Se pica
- Rasca para quitar o ferrete da abella e arrefría a zona.
- Se a persoa ten dificultade para respirar, a cara ou a gorxa inchadas, ou sente que se vai desmaiar, é unha emerxencia alérxica: chama ao teu número de emerxencias e usa o seu autoinxector de adrenalina se ten un.
Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos
Mantente a salvo
- Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
- Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
- Se un te pica: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.
Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos
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
