The goldenrod crab spider is a small, flat spider that hides on flowers and waits for insects to land nearby. It lives in Europe and North America. It is named for the way it walks, and it can change its colour to match the flower it sits on.1

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zer egiten du bere pozoiak?

Its venom is paralysing, which means it stops prey from moving. The spider injects digestive enzymes with its fangs to break down the insides of its prey. The venom is too weak to harm larger animals.1

Zein arriskutsua da pertsonentzat?

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

This spider is harmless to humans. Its fangs are not strong enough to pierce human skin, and its venom is too weak to harm larger animals.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

jakin beharrekoa

Datuak

Females can change colour from yellow to white, or back again, to match the flower they sit on. This process can take up to 25 days.1

The spider can catch prey much larger than itself, because its paralysing venom works so well.1

Unlike many spiders, it does not wrap its prey in silk. It relies entirely on venom to hold its meals still.1

Females leave silk trails called draglines behind them as they move, and males follow these trails rather than pheromones.1

Females wait on flowers and do not travel far, while males roam over great distances to look for mates.1

Females live longer than males, on average.1

Mito-hauslea

Mitoa: Because it is a venomous spider with a name like Whitedeath, it is dangerous to people.

Egia: The goldenrod crab spider is harmless to humans. Its fangs cannot pierce human skin, and its venom is too weak to harm larger animals.1
