Southern yellowjacket

Vespula squamosa

只是会疼会疼，但不会对你造成严重伤害。

蜇伤吃：肉

The southern yellowjacket is a social wasp with black and yellow stripes and an orange queen. It lives in eastern North America and further south into Central America. Its nests are often in yards, parks and by roads, so people meet it often, and its stings are painful.1

首页

Nests are usually in unnatural or disturbed places such as yards, parks, picnic tables and roadsides, and in wall voids. Some colonies are in pine forests or hardwood forests. Most nests are underground, though some are above ground or in walls. The species is common in urban areas.1

它吃什么？

It is predatory and mainly eats live insects, especially arthropods such as spiders and caterpillars. It also feeds on the flesh of dead prey. Adult workers bring food back to the larvae in the nest.1

怎样认出它

Black body with yellow striping over the whole body1
Clear wings and a hairless body1
About 1.3 cm long1
The queen is larger than the males and workers and is more orange in colour1
Has two stripes on its scuta1

常被误认为： Its two stripes on the scuta are shared with V. sulphurea. The queen looks different from the workers and males, so check the colour and size of the wasp you see.1

毒液通过蜇刺出来。

它的毒液会造成什么？

Its stings are venomous, and the venom causes pain. Workers can sting several times in one attack.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。

The species is considered a pest because its nests are close to people and can be large. Close contact with people commonly leads to multiple, painful stings. Disturbing a nest can result in several stings.1

它害怕时会做什么？

Workers release alarm pheromones that signal the rest of the colony to attack whatever threatens the nest. Their stings are typically used in defence of the colony.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

Most southern yellowjackets are social parasites: they build their nests around the nests of another species.1

About 85% of colonies start when a queen takes over a small nest of the eastern yellowjacket, V. maculifrons, and only about 15% are founded independently.1

Some nests are very large. One of the biggest reported was in a pine tree and the dirt beneath it, and it had over 50 combs in the trunk alone.1

In Florida and other southern coastal areas, some nests survive the winter and last for several years.1

Workers and queens use pheromones to communicate, with alarm signals for attacks and a different pheromone that attracts males to the queen.1
