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

E phela

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

Yuropa

Lapeng

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

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

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

Dintlha

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
