The hobo spider is a brown spider that lives in fields, woods and under rocks in Europe, Central Asia and western North America. It builds a funnel-shaped sheet of silk and waits at the narrow end for insects to crawl on. It sometimes builds webs in or around homes, so people often worry about its bite.1

Tuis

Hobo spiders live mostly in fields, woods and under rocks. They sometimes build webs in or around human homes. They often make a horizontal, trampoline-like web near brick walls or wood piles, where they have shelter and wait for prey.1

Wat eet dit?

Hobo spiders catch prey insects that blunder onto their funnel webs. They wait at the small end of the funnel for the insects to arrive.1

Hoe om dit te herken

Body length is 7 to 14 mm, and the spider is brownish in colour.1
The abdomen has V-shaped chevron patterns down the middle, pointing towards the head.1
There is a light stripe running down the middle of the underside (sternum).1
There are no coloured bands where the leg joints meet.1
The top of the front body section (cephalothorax) has indistinct or diffused patterns, not two distinct dark stripes.1

Word dikwels verwar met: Other Eratigena species have three or four pairs of light spots on the sides of the sternum rather than a central stripe, though these spots can be very faint. Spiders in the genera Agelenopsis and Hololena, and possibly some wolf spiders, have two distinct dark stripes on the top of the front body section. Positive identification of hobo spiders usually requires microscopic examination of their sex organs by an expert.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

There is no clear evidence that the hobo spider has venom that is dangerous to humans. Earlier case reports linked its bites to isolated cases of necrosis, which is the death of skin tissue, but this is no longer supported.1

Hoe gevaarlik is dit vir mense?

There is little evidence that the hobo spider is dangerously venomous. The US CDC no longer lists it among venomous species, as of 2017. In Canada there is no evidence that its bites cause skin necrosis.1

As dit byt

Was die byt en sit 'n yspak daarop vir die pyn. Kry mediese hulp as die pyn erg is, versprei of die persoon sleg voel.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

In Europe, hobo spiders mostly avoid houses because the larger giant house spider lives there and competes with them, so human contact is uncommon.1

The male hobo spider dies after mating.1

A hobo spider was probably carried to the small artificial Danish island of Peberholm by trains.1

Mite-breker

Mite: Hobo spiders have dangerous venom that causes skin necrosis.

Waarheid: There is little clear evidence that the hobo spider's venom is dangerous to humans. Some bites reported as hobo spider bites may have been from the desert grass spider.1
