只是会疼会疼，但不会对你造成严重伤害。

蜇伤

The dark paper wasp is a social wasp that lives across eastern North America, from southern Canada to Texas and Florida. It often builds its papery nest near people, especially where wood is easy to find. Only the females can sting, and they live in colonies with a clear pecking order.1

它吃什么？

Adults bring back nectar, pulp and prey to the nest. The workers and foundresses use wood fibres to make the nest material.1

怎样认出它

Slender body with a narrow waist between the chest and the abdomen1
About 15 to 21 mm long1
Northern females are mostly black all over, and may or may not have other markings1
Southern individuals often have yellow or brown and black markings on the face and abdomen, and the patterns vary a lot1
Males have darkened tips to their antennae1

常被误认为： Southern individuals often have extra markings and can resemble wasps of other species. Northern females are usually almost entirely black, which can help tell them apart.1

它的毒液会造成什么？

Only the female has a venomous sting. The pain is commonly compared to being pricked with a large needle, such as a tattoo needle.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？

Colony members defend the nest together, and the foundress is the most aggressive defender because she has the most invested in the colony.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

事实

Non-resident wasps are often chased out of the nest within the first five minutes of entering it.1

Dominance in the colony depends on fertility, and wasps with larger or more developed ovaries usually rank higher.1

Another wasp species, Polistes dominula, has been displacing this species in many areas where it once dominated.1

A colony can contain well over 200 wasps.1
