Zer jaten du?

It usually eats small insects and household pests that get caught in its web. If prey is too quick, it shoots web at it from a distance and then pulls the thread back in. Larger females can even attract baby skinks by hanging fly remains in their web.1

Its bites are not known to be dangerous to humans. It bites people only in self-defence, when it is grabbed and squeezed.1

Zer egiten du beldurtzen denean?

It runs to a secure hiding place when it senses movement, and if cornered it plays dead as a last resort.1

Kosk egiten badu

Garbitu koska eta jarri izotz-poltsa bat gainean minerako. Lortu mediku-laguntza mina handia bada, zabaltzen bada edo pertsona gaizki sentitzen bada.

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

The assassin bug Stenolemus lanipes apparently feeds only on its young, though it can also eat adults.1

When food dries out, it usually drops it to the floor to free up space in its web, rather than rebuilding the web.1

It has poor eyesight and cannot detect movement more than three to four inches away.1

Males and females often share the same web for long periods, though females sometimes fight when they meet.1

Mito-hauslea

Mitoa: Common house spiders are dangerous to people.

Egia: Their venom is neurotoxic, but their bites are not known to be dangerous to humans. They bite only when grabbed and squeezed.1
