The noble false widow is a spider that looks a lot like the black widow, which is why it has its name. It is now found in many parts of the world, including Europe, the United States and New Zealand, and it is one of the world's most invasive spiders. Its bite can be painful, so it is worth knowing what it looks like.1

Leef in

Native to Madeira and the Canary Islands. Now established across Europe, parts of the USA, North Africa, Chile, Colombia, Ecuador and New Zealand.1

Europa, Afrika

Tuis

It lives both indoors and outdoors all year round, in places such as cacti, agave, roadside cuttings, demolished buildings, telegraph poles, concrete fence posts and ivy on walls. Seaside cities and villages with a mild climate are especially good places for it.1

Lengte

Wat eet dit?

It eats both insects and other spiders, woodlice, and small vertebrates such as pipistrelle bats and a pygmy shrew. It catches prey with an 'attack wrap', wrapping silk around the victim while it bites, and its venom quickly paralyses the prey.1

Hoe om dit te herken

The abdomen (rear body) is brown and rounded, with cream markings that are often said to look like a skull.1
The legs are reddish-orange.1
Adult females are about 9.5 to 14 mm in size, and males are about 7 to 11 mm.1
It is larger than other spiders in its genus, Steatoda, and has a typical colour pattern.1

Word dikwels verwar met: It is often mistaken for the black widow (Latrodectus) and other false widow species. It can be told apart from the black widow by its larger size within its genus and its typical colouring, though many spiders in this group look similar.1

Gifkrag

Byte

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

Wat doen sy gif as dit byt of steek?

Most of its venom is made of toxins similar to those of the widow spiders, mainly alpha-latrotoxin. This toxin makes holes in nerve cells, which releases chemical messengers and blocks the signals between nerves and muscles, causing paralysis. In people, the venom is most noticeable as pain at the bite site, along with swelling, redness and fever.1

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

It is considered moderately medically significant. Most bites cause symptoms similar to a bee or wasp sting, but some can be more serious, partly because of bacteria. It is considered one of the most dangerous spiders in western Europe. Bites from males are less severe than bites from females, and the bite itself is usually painless, with pain coming from the venom.1

As dit byt

Without proper treatment, a bite wound can become infected and develop into gangrene or sepsis, so medical care should be sought.1
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.

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

The spider often catches prey much larger than itself, including bats, because its venom works quickly.1

It can survive without drinking water, getting all its liquid from its prey.1

Males court females by tapping the web and vibrating their bodies, and they can make scraping sounds with their abdomens.1

It has poor eyesight and relies mainly on vibrations travelling through its web.1

It produces three-dimensional cobwebs, and its silk is unusually strong for its genus.1

One adult female lived almost five and a half years in captivity, and adult females are long-lived.1

Mite-breker

Mite: It is the same spider as the black widow.

Waarheid: It only looks similar to the black widow. It belongs to the genus Steatoda, while the black widow belongs to the genus Latrodectus.1
