The yellow garden spider is a large, colourful spider with yellow and black markings on its abdomen. It builds big round webs in sunny fields, gardens and along the eaves of houses in North America, Mexico and Central America. It bites only if disturbed or handled, and its bite is comparable to a bee sting.1

首页

Yellow garden spiders build webs in open, sunny fields, where they stay concealed and sheltered from the wind. They are also found along the eaves of houses and outbuildings, and in any tall vegetation where a web can be stretched securely.1

在陆地上, 粗略估计

它吃什么？

The spider waits in the centre of its web for prey to become trapped. It may shake the web back and forth to trap the insect further, then kills the prey with venom and wraps it in a silk cocoon to eat later, typically 1–4 hours afterwards. Prey includes insects and small vertebrates such as geckos and green anoles.1

怎样认出它

Yellow and black markings on the abdomen (the rear part of the body).1
A mostly white front body section (cephalothorax).1
A large, circular web up to 60 cm across, with a dense zigzag of silk in the centre.1
The female sits in the centre of the web, usually facing straight down.1
Females measure 19–28 mm in body length, while males are much smaller at 5–9 mm.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？

The venom contains polyamine toxins, including one called argiotoxin ArgTX-636, which are being studied for possible medical uses. For most people the venom is harmless, and a bite causes redness and swelling, similar to a bee sting. It is harmless to people who are not allergic.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。

These spiders are not aggressive and only bite if grabbed or disturbed. For a healthy adult, a bite is not considered an issue. People who are very young, elderly, or have weakened immune systems should take the same care they would around a beehive or hornet nest.1

它害怕时会做什么？

If disturbed by a possible predator, the female may drop from her web and hide on the ground nearby, and she can shake the web vigorously while staying attached in the centre.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

The female can shake her web vigorously to make it harder for wasps and birds to target her, and to fully tangle an insect before it cuts itself free.1

After mating, the male often dies and is sometimes eaten by the female, as he inserts his second palpal bulb.1

The zigzag silk in the web, called a stabilimentum, may camouflage the spider, attract prey, or warn birds away, but its purpose is still disputed.1

In a case observed in Georgia, a European hornet cut free prey caught in a yellow garden spider's web, and the spider did not fight it, probably because it dropped from the web and hid.1

谣言粉碎机

谣言： Yellow garden spiders are dangerous and their bite can seriously harm a healthy adult.

真相： The venom is harmless to people who are not allergic. A bite is comparable to a bumblebee sting and is not considered an issue for healthy adults.1

宝宝: Each female produces one to four egg sacs, each holding perhaps over a thousand eggs, and in spring the tiny spiderlings emerge and some are carried away on silk strands by the breeze.1
