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

Zer jaten du?

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

Askotan honekin nahasten da: 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

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zein arriskutsua da pertsonentzat?

Arriskua pertsonentzat: ArinaErle-ziztada bat bezala edo gutxiago. Ia kaltegabea pertsonentzat.

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

Zer egiten du beldurtzen denean?

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

Egon seguru

Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.
Batek kosk egiten badizu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago

Datuak

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

Mito-hauslea

Mitoa: This spider is aggressive and will attack people.

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