The black house spider is a dark, sturdy spider that lives across Australia. It was carried to New Zealand and Japan, and it often lives in homes, where it sits in a messy web in corners and near windows. It is venomous, but its bite is rarely a serious danger to people.1

它吃什么？

The spider waits in its funnel-shaped retreat for insects to land in its web. Young spiders catch smaller prey that the larger female ignores.1

怎样认出它

A dark, robust spider. Females have a body up to 18 mm long and a leg span of 30 mm.1
Males are smaller, about 10 mm long, with longer legs in proportion to their body.1
The body and legs are dark brown to black. The abdomen (rear part) is charcoal grey, with light markings that are sometimes faint, and it is covered in fine, velvety hair.1
The web looks messy, with irregular sail-like sheets of silk and a funnel-shaped retreat, usually in the middle or corner of the web.1

常被误认为： The grey house spider (Badumna longinqua) is similar and has a similar range. It is slightly smaller, at about 14 mm, has a greyish top section (carapace) and black-brown legs. It is more often found outdoors.1

对人的危险: 很疼可能真的很疼，但几乎从不严重。

值得了解

事实

A male plucks the female's web to attract her attention before he approaches to mate. They may stay together for several days and mate several times.1

The spider rarely moves its web, so old webs become messy, with dust and small objects stuck in them.1

At night, the spider repairs and adds to its web, often by laying new silk over the old.1

The female almost never leaves her web unless she is forced to.1

Predators include the white-tailed spider, as well as parasitic wasps and flies.1
