Jumping Spiders

(Family Salticidae)

Male jumping spiders are smaller than females. Some jumping spiders are black and have white markings on their abdomen. Others have metallic green chelicerae and are iridescent.

Jumping spiders are quite small, ranging from ½ inch and smaller.

[jbox title=”Interesting Fact”] Jumping spiders only bite when they are disturbed, as a form of self defense. If you are bit by a jumping spider, it might hurt, but there will not really be any other effects.[/jbox]

Just as the name implies, jumping spiders can jump. Their bodies are able to move when the blood pressure rises and is released in their limbs, making the circulatory system the reason they are so fast and jumpy. They are known to be among the fastest moving spiders around and can jump approximately 10 to 40 times their body length.

Jumping spiders have fantastic eyesight. Four eyes are connected to their face, and four are on the carapace at the highest point. Two of the eyes in the center of their face are long and tube-like. Those eyes have very high resolution, but not very good perspective. The other two eyes on the face have greater perspective, but not very good resolution.

Jumping spiders typically eat insects, although some also eat web-building spiders.

Outdoors, jumping spiders live in yards, grasslands, and prairie areas. Indoors, they live in barns and houses near windowsills and near doorjambs.
