The golden silk orb-weaver is a large spider with silk that shines golden in sunlight. It lives in forests and wooded areas from the southern United States to Argentina. It is special because its silk is studied by scientists, and because it is one of the largest non-tarantula spiders in North America.1

它吃什么？

It catches small and medium-sized flying insects in its large web. It subdues prey by injecting venom, unlike related species that wrap prey in silk first.1

怎样认出它

Females have a silvery white front body (cephalothorax) and a longer orange-brown abdomen with two rows of small white-yellow spots.1
Females have dark yellow and brown banding on their legs, with black brush-like tufts of hair near the joints of the first, second and fourth leg pairs.1
Females are about 24 to 40 mm long when fully grown.1
Males are much smaller, about 6 mm long, with a plain dark brown body and legs.1
The large webs are circular and vertical, and the yellow pigment in the silk gives them a golden glow in good light.1

常被误认为： Trichonephila plumipes also has stiff hairs on its legs. In that species the hairs are set more closely together than in the golden silk orb-weaver.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 has low toxicity. It is relatively harmless and poses little health concern to healthy adult humans.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。

It is not known to be aggressive towards humans. It bites only in self-defence if it is touched, and its venom poses little health concern to healthy adults.1

它害怕时会做什么？

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

Its silk may help in surgeries involving the nervous system, as shown in past experimental studies.1

It produces seven different types of silk, and its silk is valued in spider silk research.1

Its genome was the first of the orb-weaving spiders to be completely annotated, revealing 28 unique genes for spider silk proteins.1

Some individuals living in developed areas have grown significantly larger than their rural counterparts.1

Males rarely suffer sexual cannibalism or genital mutilation, unlike males of many related species, which makes it a focus of study into spider mating.1

Females are some of the largest non-tarantula spiders in North America, and may be the largest orb-weaver species native to the United States.1
