The goldenrod crab spider is a small, flat spider that hides on flowers and waits for insects to land nearby. It lives in Europe and North America. It is named for the way it walks, and it can change its colour to match the flower it sits on.1

It eats insects such as flies, bees, butterflies, grasshoppers, dragonflies and hoverflies. It waits camouflaged on flowers, grabs its prey and injects venom and digestive enzymes, then sucks out the liquid insides.1

怎样认出它

Wide, flat, short body that is shaped like a crab.1
Usually yellow or white, or a pattern of these two colours. It can also be pale green or pink, with white.1
Females have white or yellow legs. Males are darker, with red or brown outer shells and red and white bands.1

常被误认为： Mecaphesa asperata is similar in size and shape, but it is light grey to brown with pink stripes on its abdomen and cephalothorax. Diaea crab spiders can be lime green, and some Xysticus and Coriarchne species are brown.1

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？

Its venom is paralysing, which means it stops prey from moving. The spider injects digestive enzymes with its fangs to break down the insides of its prey. The venom is too weak to harm larger animals.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。

This spider is harmless to humans. Its fangs are not strong enough to pierce human skin, and its venom is too weak to harm larger animals.1

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。

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

值得了解

事实

Females can change colour from yellow to white, or back again, to match the flower they sit on. This process can take up to 25 days.1

The spider can catch prey much larger than itself, because its paralysing venom works so well.1

Unlike many spiders, it does not wrap its prey in silk. It relies entirely on venom to hold its meals still.1

Females leave silk trails called draglines behind them as they move, and males follow these trails rather than pheromones.1

Females wait on flowers and do not travel far, while males roam over great distances to look for mates.1

Females live longer than males, on average.1

谣言粉碎机

谣言： Because it is a venomous spider with a name like Whitedeath, it is dangerous to people.

真相： The goldenrod crab spider is harmless to humans. Its fangs cannot pierce human skin, and its venom is too weak to harm larger animals.1
