The Jumping Spider
The Jumping spider belongs to the family Salticidae. They get their popular name from their ability to jump to catch preys.

HOW TO IDENTIFY JUMPING SPIDERS
Jumping spiders are usually black, sometimes brown, grey, or tan in color with lighter markings. They have relatively smaller legs than other spiders. The jumping spiders are about 4 to 18 mm in size and covered with bright hair all over their bodies.
Appearance and Behavior
Jumping spiders have black compact bodies with relatively shorter legs. They are often mistaken with black widow spiders. Their bodies are covered with bright hair, but their body color can vary from black to brown, grey, or tan, with pale marks.
These spiders are usually 4-18mm in size. Their front legs are a bit longer than the back ones and they have 8 eyes in three rows. The first row consists of 4 eyes, with 2 very large ones.
The most distinctive feature of these spiders is that they can jump, and they use this ability to catch prey. Thus, they make their webs only for protective purposes, not for hunting. Jumping spiders are venomous creatures, they can kill insects by injecting venom into their bodies.
However, they are almost harmless to humans since they are unable to inject venom in large quantities. Their bites can cause some allergies and redness but no serious consequences have been reported. Jumping spiders have great vision and are able to detect movement up to 45 cm but their night vision is not so good.
