Noble false widow

Steatoda nobilis

O mene: It is called a false widow because it looks like the black widow spider, although it belongs to a different group of spiders.1

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

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

Domov

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

Čo je?

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

Ako ho spoznať

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

Často sa zamieňa s: 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

Sila jedu

Uhryznutia

Jed vychádza cez jedové zuby, keď hryzie.

Čo robí jeho jed?

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

Aké nebezpečné je pre ľudí?

Nebezpečenstvo pre ľudí: BolestivéMôže to poriadne bolieť, ale skoro nikdy to nie je vážne.

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

Ak uhryzne

Without proper treatment, a bite wound can become infected and develop into gangrene or sepsis, so medical care should be sought.1
Umy miesto uhryznutia a daj naň ľadový obklad na bolesť. Vyhľadaj lekársku pomoc, ak je bolesť silná, šíri sa alebo sa postihnutý cíti zle.

Buď v bezpečí

Nikdy sa nedotýkaj divého zvieraťa, nechytaj ho ani ho nedráždi, aj keď je malé a aj keď vyzerá, že spí alebo je mŕtve.
Nechaj mu priestor. Ak nejaké stretneš, zostaň pokojný, pomaly cúvni a nechaj ho ísť svojou cestou.
Ak ťa uhryzne: zostaň pokojný, nehýb sa, zavolaj na tiesňovú linku (112, 000, 911) alebo sa rýchlo dostaň do nemocnice. Zapamätaj si, ako vyzeralo, fotka pomôže.

Nejde po tebe. Jed používa na chytanie potravy alebo na obranu a oveľa radšej sa schová. Viac o tom, ako zostať v bezpečí

dobré vedieť

Fakty

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

Lovec mýtov

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

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