Wasp spider

Argiope bruennichi

无害对人无害。不用担心。

咬伤吃：肉

The wasp spider is an orb-weaver spider with bold yellow, white and black stripes on its abdomen, which look a bit like a wasp. It lives across Central and Northern Europe, parts of Asia and Africa, and the Azores. Its unusual mating habits make it one of the most studied spiders of its kind.1

它吃什么？

It catches insects in its spiral web. When prey is trapped, the spider wraps it in silk to immobilise it, then bites it.1

怎样认出它

Yellow, white and black markings on the abdomen1
Females have a body length of 14 to 20 mm, and are much larger than males1
A zigzag-shaped decoration, called the stabilimentum, runs through the centre of the orb web1
Builds its spiral orb web at dawn or dusk1

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

The spider injects its prey with a paralysing venom, which stops the prey from moving, and a protein-dissolving enzyme, which breaks down the prey's body tissues.1

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

如果它咬人

清洗咬伤处，用冰袋冷敷止痛。如果疼得厉害、疼痛扩散或感到不适，就去看医生。

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。
如果被它咬了：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

Females often eat the males after mating, a behaviour called sexual cannibalism. Males improve their chances by waiting near an immature female's web until she moults into adulthood, when her jaws are still soft. In one study, this raised male survival from 20% to 97%.1

Some males block other males from mating with the same female. They do this by losing one of their pedipalps, which allows them to mate only twice.1

Males are small enough to enter a female's web without being detected, which helps them mate.1

Webs with a stabilimentum are damaged less often by birds flying through them, although its exact purpose is not known.1

In summer 2006, researchers found an influx of wasp spiders in the UK. The yellow stripes on this population are more cream-coloured.1
