蜇伤吃：什么都来一点

对人的危险: 很疼可能真的很疼，但几乎从不严重。

The ringed paper wasp is a large, red-and-black wasp that lives across the eastern half of the United States. It builds papery nests under overhangs, often close to rivers and lakes, and many nests are grouped together in big clusters. Its red-faced look is easy to spot once you know what to look for.1

首页

Nests hang from branches of trees and shrubs, and sometimes in sheltered parts of buildings. Large groups of nests are often built on the underside of rocky cliff overhangs close to rivers, where they are shaded for most of the day.1

它吃什么？

Adults feed on nectar and also eat other insects. Foraging workers bring chunks of caterpillar back to feed the larvae.1

怎样认出它

Rust-red head and thorax (the middle part of the body)1
Mostly black abdomen with a single, prominent yellow ring at the end of the first segment1
Bright orange tips on the antennae (feelers)1
Narrow first abdominal segment1
Males and females both have red faces, which is unusual among North American paper wasps1

常被误认为： Darker P. bahamensis lacks the yellow markings on its mesopleuron (side of the middle body) and has less yellow on its mesosoma. Metricus and darker forms of P. fuscatus have no contrasting orange antennal tips and a wider first abdominal segment.1

毒液通过蜇刺出来。

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？

Co-foundresses on the nest defend it, and the nest is hung on a stalk that keeps many predators away.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 related species, it is fairly tough in winter, and it stores concentrated nectar as a kind of honey before hibernating.1

Its colours closely match those of P. metricus, which lives in much the same area, so the two look alike to predators.1

Several females can share one nest, with up to 22 cooperating foundresses recorded in a single group.1

A single nest can hold around 500 cells, far more than the nests of many other paper wasps in its genus.1
