蜇伤

The Guinea paper wasp is a social wasp that builds small, open nests in colonies of up to about one hundred individuals. It lives in parts of North America, including the eastern United States, Ontario in Canada, and Mexico. Its colonies are often found near buildings and other man-made structures.1

Nests are built in well-lit, open sites, often on or near man-made structures. Nests are made of paper-like comb with a single layer of hexagonal cells and no outer paper envelope. They hang downward from one filament. This wasp will also use artificial nests, such as bundles of straws.1

怎样认出它

Typical form: mostly yellow markings on the back of the thorax and the propodeum (the rear part of the thorax), and wings that are purple-tinged rather than yellow.1
Variable form: red-brown body with dark, almost black, markings on the middle of the antennae, the bases of the abdominal segments and the wings, and pale ivory-white markings spread across the body.1
Antennae banded with red, black and yellow, unlike most paper wasps, which have only one antenna colour.1
Females have forewings of 13.0 to 16.5 mm; males have forewings of 12.0 to 15.0 mm.1
Males have bulging eyes and slender antennae.1

常被误认为： The typical form is often confused with Polistes fuscatus, Polistes crinitus and Polistes minor.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

事实

Queens survive cold better than workers. In one test at 5 °C over 15 days, 76% of queens survived compared with 17% of workers, partly because they build up sugars that act as antifreeze and a layer of body fat.1

When a queen dies, the oldest female worker becomes the new queen, because the colony ranks its members by age.1

Whether a wasp becomes a worker or a queen is set by the temperature it experiences as an immature wasp.1

Nests are small, usually with fewer than one hundred individuals, so the queen is often the most active wasp in the nest and directly controls the nest's activity.1

Out of six wasp species studied, this was the only one that nested in artificial sites.1
