Southern house spider

Kukulcania hibernalis

无害对人无害。不用担心。

咬伤吃：昆虫

The southern house spider is a large spider that lives in the Americas, from the southern United States to Argentina. It is often mistaken for the brown recluse, but it is not aggressive and rarely bites. Its males wander around looking for mates, and both sexes can squeeze through very narrow cracks.1

它吃什么？

It catches insects in its web. It combs silk across a spiked plate called the cribellum, which frays the threads into a fine, velcro-like net that catches insect legs.1

怎样认出它

Females are dark brown or black and more compact in shape, with often larger, bulbous bodies.1
Males have longer legs and unusually long, slender pedipalps (the leg-like feelers near the mouth).1
Males lack the violin-shaped marking on the front part of the body that the brown recluse has.1
The abdomen (rear part of the body) is covered in fine, velvety light grey hair.1
Both sexes may grow to about 5.1 cm across with legs extended.1

常被误认为： Males are often mistaken for the brown recluse because they have similar colours and body structure. Male southern house spiders are usually larger, have no violin shape on the front of the body, and have long, slender pedipalps.1

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

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。

Males may seem aggressive, but they bite only when trapped. Their mouthparts are too small to easily get through human skin, so bites are unlikely to be harmful.1

它害怕时会做什么？

When it feels threatened, it instinctively plays dead, a tactic that works well against its common predators.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。

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

值得了解

事实

It is a cribellate spider, meaning its silk is not sticky. Its web works by tangling silk into a velcro-like net.1

It can crawl through cracks as narrow as 0.66 cm, thanks to its long body and compact legs.1

It is almost blind, so it may crawl over anything in its path, living or not, without meaning to attack.1

Its mating ritual can last over an hour, with long pauses where neither spider moves much.1

Its family, Filistatidae, is known as the crevice weavers because the females build webs around cracks.1

谣言粉碎机

谣言： Southern house spiders are aggressive and bite people often.

真相： Males may look aggressive, but they bite only when trapped, and their mouthparts are too small to easily penetrate human skin. Their crawling over things is not aggression, as they cannot see larger animals.1
