Red & Black Spider


Habitat and Biology: 
In summer, males leave their web, during daylight hours, and wander in search of females. This wandering habit often brings them indoors. Due to the red and black colour, the spider is often confused with the red-back spider and, as red is a common warning colour, the spider is sometimes thought to be highly venomous. The egg case has a woolly appearance and is suspended in the web.

Male: Similar to female.
Female: Body and legs commonly bright red, abdomen black, but varying orange to dark red, sometimes with a bluish tinge.

Typically a small spider with slender legs, most easily recognised by colour pattern as described above.

Despite the red colour of this spider its venom is not dangerous. At most, it may cause a local reaction around the bite site. Normal precautions, as outlined in the introduction, should be observed.
