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

它吃什么？

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

怎样认出它

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

常被误认为： 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

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

它害怕时会做什么？

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

如果它蜇人

刮掉蜜蜂的蜇针，冷敷患处。
如果这个人呼吸困难、脸或喉咙肿胀，或感觉要晕倒，这是过敏急症：拨打急救电话，如果他们有肾上腺素笔就使用。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

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
