Guinea paper wasp

Polistes exclamans

只是會痛會痛，但不會對你造成嚴重傷害。

螫

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

怎麼認出牠

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

常被誤認為： The typical form is often confused with Polistes fuscatus, Polistes crinitus and Polistes minor.1

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

如果牠螫人

把蜜蜂的螫針刮掉，然後冷敷患處。
如果傷者呼吸困難、臉部或喉嚨腫脹，或覺得快要昏倒，這就是過敏急症：打緊急電話，如果傷者有腎上腺素自動注射筆，就使用它。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠螫了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

值得知道

小知識

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
