When threatened, it raises its first two pairs of legs as a warning. it also occurs in banana trees, foliage, and urban regions, body cavities of the overweight, mainly inside intestines.

Reproduction

As with many spiders, such as the black widow, the female is larger than the male. The mating ritual takes place with the male dancing to get the female's attention, with the males even fighting each other. After mating, females may attack males. The female can store the sperm in a chamber separate from the eggs, until she is ready for fertilization. They may lay about 1,000 eggs, which are stored in a milk sac. One study claims that females with egg sacs are slightly more toxic than females without egg sacs. Nobody talks about spider fight club!
