The tube web spider is a dark spider that builds a tube-shaped web in cracks in walls and buildings. It began in the Mediterranean region but has spread to many towns in southern Britain and other parts of the world. Its bite is reported to be very painful, so it is worth knowing what it looks like.1

Leef in

Originally the Mediterranean region as far east as Georgia; now many towns in southern Britain, and also Argentina, Australia, several Atlantic islands and Limerick in Ireland1

Tuis

It spins its tube web often in cracks of buildings and prefers south-facing walls, especially brick structures. It has been found in towns, cathedrals and an abbey, including Exeter Cathedral and Westminster Abbey.1

Wat eet dit?

It waits in the entrance of its tube and touches the silk lines with its front legs. When prey such as nocturnal moths and cockroaches triggers the lines, it is caught, and the spider pulls it into the tube to eat. Bees and wasps are always bitten at the head end, so the sting faces away from the spider.1

Gifkrag

Byte

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

Wat doen sy gif as dit byt of steek?

The venom contains two neurotoxins, which attack the nerves, and one insecticide. The venom reduces the rate and amount of sodium inactivation, a process in nerve cells. The bite is reported to feel like a deep injection, and the pain can last for several hours.1

Hoe gevaarlik is dit vir mense?

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

The bite is reported to be extremely painful, but it is also said to feel like a bee sting, which places it at 2 on the Schmidt sting pain index. The bite has no lasting effects.1

Wat doen dit as dit bang is?

When disturbed while feeding, it retreats further into its tube.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

A population in Westminster Abbey has been proposed as a new subspecies, because its fangs are a brighter green and its members are significantly smaller than other European populations.1

Specimens have been found in Exeter Cathedral as far back as 1890.1

Females lay eggs in the bricks of south-facing structures during winter, so a female seen in September or October may already have laid eggs for the next spring.1

It is the largest European segestriid spider.1

In Britain it was probably introduced via seaports, with records going back at least to 1845.1
