蜇伤吃：什么都来一点

The median wasp is a social wasp that lives across Europe and temperate Asia, as far east as Japan. It builds hanging paper nests in shrubs and trees, and sometimes under the eaves of buildings. It is usually calm, but it will sting if its nest is threatened.1

它吃什么？

Workers forage for insects, nectar and wood for building the nest. As it searches for prey, it pauses briefly over each flower. Larvae are fed small amounts of flesh, and adults also take liquid food.1

Yellow and black stripes on the abdomen1
Yellow clypeus (the face plate below the eyes) with a thin black central line1

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 median wasp is not usually aggressive. It will sting if it feels its nest is threatened, so keep well away from nests.1

它害怕时会做什么？

A disturbed wasp first places its head at the nest entrance in an alert position, then flies quickly around the nest and may drop suddenly to the ground.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

事实

Sisters share 0.75 of their genes by descent, which is higher than the 0.5 shared between full siblings, because of how sex is determined in this order of insects.1

The queen curls her body around the nest's central stalk, which is thought to help keep eggs and larvae warm.1

Workers sometimes police the nest, with the queen or other workers destroying eggs laid by other workers.1

Workers can forage at temperatures as low as 7 °C (45 °F).1

Its nests are made of paper pulp produced by chewing and digesting wood.1
