The red paper wasp is a social wasp that builds papery nests from chewed plant fibres and saliva. It lives across much of the Neotropical region, from southern Arizona down to Argentina. Its colonies share work between many females, which makes it a useful example for scientists studying how social animals organise themselves.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。

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

A single queen dominates the other females, sometimes using physical attacks that can turn into fatal battles.1

Colonies build many combs, often around 38 in total, and move brood into new combs as old ones are abandoned. This is thought to protect the colony from moth infestations.1

Male wasps follow two mating tactics: some defend territories, while smaller males patrol from tree to tree and sneak matings when they can.1

Around 56% of females drift to nearby nests, which helps protect the colony against predators. An egg has a 40% chance of being eaten by a predator before it reaches adulthood.1

Colonies are founded or abandoned at any time of year, so their development is not tied to the seasons.1

谣言粉碎机

谣言： The species name canadensis shows that this wasp lives in Canada.

真相： Linnaeus was misinformed about where his specimen came from. In North America, this wasp only reaches as far north as southern Arizona.1
