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

Kaj je?

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

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

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

Kaj naredi, ko se prestraši?

When disturbed while feeding, it retreats further into its tube.1

Če ugrizne

Ugriz umij in nanj daj ledeni obkladek proti bolečini. Poišči zdravniško pomoč, če je bolečina močna, se širi ali se poškodovanec slabo počuti.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti

Dejstva

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
