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

Anaishi

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

Amerika Kaskazini

Nyumbani

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

Urefu

1.5 cm (0.6 in)3

ukubwa wa kawaida wa mnyama mzima

Kasi ya juu

Hula nini?

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

Jinsi ya kumtambua

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

Mara nyingi huchanganywa na: 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

Hufanya nini akiogopa?

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

Akidunga

Kwangua mwiba wa nyuki na upoze mahali hapo.
Mtu akipata shida ya kupumua, uso au koo likivimba, au akijisikia kuzimia, hiyo ni dharura ya mzio: piga namba ya dharura na umtumie kalamu yake ya adrenalini kama anayo.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

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
