The barn funnel weaver is a spider that often shares homes with people. It builds funnel-shaped webs in corners of houses, sheds and cellars. It is shy and rarely bites.1

ホーム

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

陸で, おおまかな予想

何を食べるの？

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

見分け方

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

よくまちがえられるのは： 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

毒パワー

かむ

かむときに、毒が牙や歯から出るよ。

人にとってどれくらい危険？

人への危険: 軽いハチに刺されたくらいか、それ以下。人にはほぼ無害。

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

こわいとき、どうするの？

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

安全に過ごそう

野生の動物には、小さくても、ねているように見えても、死んでいるように見えても、ぜったいにさわったり、つかまえたり、からかったりしないこと。
近づかないで。出会ったら落ちついて、ゆっくりあとずさりして、そのまま行かせてあげよう。

データ

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
