Missouri has several species of ground crab spiders in the genus Xysticus. They are usually dull gray or brown with brown, white, or yellow markings. They typically live under bark or on the ground in leaf litter.

The tan jumping spider usually lives on tree trunks. Its gray, tan, and brown coloration camouflages it against tree bark. There is usually an undulating pattern on the abdomen.

A wolf spider doesn't spin webs to catch its prey — it runs it down like a wolf! Spiders in this family have long legs and are usually gray, brown, black, or tan with dark brown or black body markings (especially stripes).

The glossy, black-bodied female black widow spider has distinctive red spots on the underside of the abdomen. Only the female can inflict a potentially dangerous bite. The small, seldom-seen male is harmless.

The filmy dome spider is one of the most abundant woodland spiders in Missouri. Although the spider is tiny, its snare web, which looks like an upside-down silk bowl, is conspicuous throughout the year.

The bold jumper, or white-spotted jumping spider, is fuzzy, makes jerky movements, jumps surprisingly long distances, and doesn't build webs. It usually has a black body with white, orange, or reddish spots on the abdomen.

Daddy longlegs, or harvestmen, are familiar Missouri animals. They are not spiders, but opilionids. Unlike spiders, they have a fused body form and lack silk and venom glands.

The color pattern can vary, but the ten-spined, chunky abdomen sets the female spined micrathena apart from all other spiders.
