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

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

Ako ugrize

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

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
