The white-tailed spider is a slim, long-legged spider that lives in southern and eastern Australia. It gets its name from the whitish tip at the end of its abdomen. It hunts other spiders at night rather than spinning a web, and it can bite people.1

They are vagrant hunters that seek out and envenom their prey rather than catching it in a web. Their preferred prey is other spiders, especially the black house spider and the brown house spider.1

The bite injects venom. Typical effects are a small red or discoloured bump that burns or itches, along with local pain and swelling. Rarely, the bite causes nausea, vomiting, malaise (a general feeling of being unwell) or headache. These symptoms are generally mild and go away over time.1

Bites are generally mild. In a study of 130 confirmed white-tailed spider bites, there were no necrotic ulcers (areas of dead tissue) and no confirmed infections. The effects were mainly local, such as pain, a red mark, swelling and itching.1

Se morde

Lava a mordedura e ponlle unha bolsa de xeo para a dor. Busca axuda médica se a dor é forte, se se estende ou se a persoa se sente mal.

Datos

Ulcers and tissue death were once blamed on white-tailed spider bites, but studies found other causes, mostly infections.1

In reported bite cases, more than 60% of people said the spider had got into their clothing, towels or bed.1

The two common species look so alike that people once thought there was only one kind of white-tailed spider.1

The white tail marking stays into adulthood, while other markings fade with each moult.1

Lampona murina has lived on New Zealand's North Island for over a hundred years.1

Desmontamitos

Mito: White-tailed spider bites cause ulcers and necrosis (dead tissue).

Verdade: A study of 130 bites found no necrotic ulcers or confirmed infections. Ulcers blamed on these spiders were shown to have other causes, mostly infections.1
