Ringed paper wasp

Polistes annularis

名字的由來： The specific name annularis comes from Latin and means 'ringed' or 'ring-shaped', which refers to the yellow ring on its abdomen.1

只是會痛會痛，但不會對你造成嚴重傷害。

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

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

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

牠吃什麼？

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

怎麼認出牠

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

常被誤認為： 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

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。

牠害怕時會做什麼？

Co-foundresses on the nest defend it, and the nest is hung on a stalk that keeps many predators away.1

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

牠有多大？

牠有多長？

大約跟一根迴紋針一樣長可以在 14 秒內飛過一整座足球場

Ringed paper wasp 跟「你」比起來有多大？

只是在你的瀏覽器裡做算術。什麼都不會儲存，也不會傳送到任何地方。

牠有多快？

一隻家蠅 大約 7 km/h (4,4 mph)

Ringed paper wasp 大約 28 km/h (17 mph)

一個正在衝刺的人 大約 37 km/h (23 mph)

值得知道

小知識

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
