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

Most nests are underground and not deep, usually covered by less than 50 mm of soil. Nests are also found in hardwood forests, on creek banks, in urban and suburban areas, and in sheltered places such as tree stumps and attics. Because nests are so often found in recreational and residential areas, it is considered a pest.1

Što jede?

It is a polyphagous species, meaning it feeds on a variety of foods. Foraging workers can learn smells, which helps them find food.1

Kako ga prepoznati

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

Često se miješa s: 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

Otrovna snaga

Otrov izlazi kroz žalac.

Što radi njegov otrov kad ugrize ili ubode?

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

Koliko je opasno za ljude?

Opasnost za ljude: BolnoMože jako boljeti, ali gotovo nikad nije ozbiljno.

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

Što radi kad se uplaši?

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

Ako ubode

Sastruži žalac pčele i ohladi mjesto uboda.
Ako osoba teško diše, ima otečeno lice ili grlo ili joj je slabo kao da će se onesvijestiti, to je hitni alergijski slučaj: nazovi broj za hitne slučajeve i upotrijebi njezin autoinjektor adrenalina ako ga ima.

Uvijek prvo nazovi broj za hitne slučajeve (112, 000, 911). Ovo su opće upute za prvu pomoć, a ne liječnički savjet. Osnove prve pomoći

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ubode: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

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
