It lives in sheltered places, including buildings. Females that live indoors often stay on the same web for years, in attics, basements, cellars and storage rooms that are rarely disturbed. Its funnel web is often built in a corner.1

在陸地上, 粗略估計

牠吃什麼？

It is an active hunter that uses good eyesight and quick movement, as well as its web. It sits at the back of its funnel and waits for prey to disturb the silk. It then rushes out, grabs the prey and drags it back into the funnel to eat.1

怎麼認出牠

Adults are typically dark orange to brown or beige, sometimes greyish.1
Its legs are striped.1
It has two dull, black stripes running along the top of the front part of its body.1
Its abdomen is mottled in brown, beige and grey, with a chevron pattern across the top, like an argyle pattern.1
Females are about 7.5 to 11.5 mm long. Males are smaller, about 6 to 9 mm, with longer, more agile legs.1

常被誤認為： It was once thought to be a close relative of the Giant House Spider. That spider has since been moved to the genus Eratigena and split into three distinct species.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

Spiders of the genus Tegenaria rarely bite. A bite only happens in self-defence, and it is unlikely to break the skin.1

牠害怕時會做什麼？

When its web is undisturbed, it retreats to the tip of the funnel and stops responding to movement. If the web is damaged, it tries to flee or curls its body into a ball against a wall or nearby object.1

如果牠咬人

清洗咬傷處，用冰敷袋冰敷止痛。如果很痛、疼痛擴散或傷者覺得不舒服，要就醫。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

小知識

In a cave between Greece and Albania, thousands of these spiders were found sharing a web over 100 square metres with another species, which is unusual for them.1

Some females living indoors in rarely disturbed places have reportedly lived for as long as seven years.1

Males usually die in autumn, soon after mating, and rarely live for more than a year.1

Its webs can become quite large if they are left undisturbed.1

Most of its eyes face forward, which helps it spot movement and focus on prey.1

破解迷思

迷思： This spider is aggressive and will attack people.

真相： It is not particularly aggressive and will often retreat when confronted.1
