Menemerus Bivittatus, commonly called the grey wall jumper or the grey jumping spider, is a jumping spider that can be found in hot and tropical regions around the world and in the South of the United States.
Grey Wall Jumper Description
As its name suggests, the grey wall jumper has a grey body color. It will often be a mixture of shades of grey, giving off the appearance of darker and light gray patches across its entire body. Their body is covered with thin, greyish-white hairs.
The grey wall jumper has two black stripes on both upper sides of its carapace and abdomen. Similarly, it has black rings around its four legs.
The larger female of the grey wall jumper can reach a size of up to 1/2 inch (1.2cm). They can take down insects up to twice their own body size.
Since the grey jumping spider is a hunter spider, it doesn’t spin a web to catch prey. Sometimes, it creates a drag line with its web during the jump as a safety line in case the jump fails.
Like the bite of any jumping spider, the bite of the grey wall spider is not dangerous to humans. Jumping spider bites are also very rare since the timid spiders usually jump away from any humans very quickly. A bite may lead to some minor swellings but will not cause any great discomfort.
