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

Their venom is used to subdue prey. In people, a bite usually causes a small red or discoloured bump, with pain, local swelling and itchiness. Rarely, it causes nausea, vomiting, malaise (a general feeling of being unwell) or headache. These symptoms are generally mild and resolve over time.1

Datos

The necrotic ulcers once blamed on these spiders were not confirmed. A scientific study found other causes, mostly infections.1

White-tailed spiders do not build webs. They hunt actively, often at night.1

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

Many people think there is only one white-tailed spider species, but the two common species look so alike that more species may still be unidentified.1

Both common species have been introduced to New Zealand, where Lampona cylindrata has spread across the South Island since 1980.1

Desmontamitos

Mito: White-tailed spider bites cause flesh-eating ulcers (necrosis).

Verdade: A study of 130 confirmed bites found no necrotic ulcers or confirmed infections. Symptoms are usually mild, with a red mark, pain, swelling and itchiness.1
