The aerial yellowjacket is a yellow and black wasp that lives across Canada and the United States. It builds grey paper nests, often high in trees, and it can deliver a sting. Its nests can be found on buildings in towns and cities.1

Leef in

Canada and the United States, from northcentral Alaska south to New Mexico and Arizona1

Noord-Amerika

Tuis

It nests in trees and shrubs, from high branches down to underground sites. In towns and cities, nests are often found on buildings.1

Lengte

1,5 cm (0,6 in)3

tipiese grootte van 'n volwasse dier

Topspoed

omtrent 24 km/h (15 mph)

Vlieënd, rowwe skatting

Wat eet dit?

Workers mostly hunt live insects and other arthropods, including grasshoppers, crickets, caterpillars, spiders, flies, lacewings and lady beetles. They also prey on fall webworm larvae and young hummingbirds. They are not usually attracted to protein baits.1

Hoe om dit te herken

Yellow in colour, with bands on the abdomen (the rear part of the body)1
No black markings on the ocular sinus (the area of the face around the eye)1
Queens have large black spots on the abdomen, with smaller spots towards the front1
Males have larger antennae and an abdomen that ends in a flat, fuzzy tip instead of a pointed sting1
Nests are made of dull grey paper, with 1 to 6 combs1

Word dikwels verwar met: It is often confused with other yellow wasps in its genus, such as Dolichovespula adulterina. The aerial yellowjacket can be told apart by the lack of black markings in the ocular sinus.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

Wat doen dit as dit bang is?

When a nest is threatened, workers can spray venom out of their sting, which releases an alarm pheromone that draws other wasps into attack.1

As dit steek

Skraap 'n byangel uit en koel die plek af.
As die persoon sukkel om asem te haal, die gesig of keel swel, of hy voel flou, is dit 'n allergiese noodgeval: bel jou noodnommer en gebruik sy adrenalienpen (outo-inspuiter) as hy een het.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou steek: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

Unlike many of its relatives, this wasp is known to spray venom out of its sting, a behaviour seen in workers from large colonies.1

Female bee moths (Aphomia sociella) sometimes lay their eggs in these nests, and their larvae can destroy large parts of the nest as they feed.1

Because nests are built high in trees, birds and other wasps are among the few predators that reach them. Skunks, opossums, raccoons and bears sometimes raid low or badly placed nests for the nutrient-rich larvae.1

Small colonies can behave unpredictably and erratically when defending their nest.1

Colonies usually last about a year before they die out as winter arrives.1
