Field Guide

Ticks drink the blood of humans and other mammals. Because they can carry serious, sometimes deadly diseases, it's important to learn about ticks and how to protect yourself from their bites.

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 whitebanded crab spider is a small, whitish-yellow or yellowish-brown crab spider commonly found in flower heads. Often its carapace is slightly greenish, with a broad whitish-yellow midband bordered by darker, thinner sides of yellowish brown.

Missouri's Neoscona spiders, called spotted orbweavers, can be hard to identify to species. Most have camouflage patterns, and they all make the characteristic, delicate, wheel-shaped webs to catch prey.

The orchard orbweaver is a small, colorful, greenish, delicate spider that makes circular webs in low bushes and damp woodlands. It typically hangs in the middle of its web, its back to the ground.

Foliage flower spiders are two genera of crab spiders. They are generally smaller than other crab spiders, and their carapaces, abdomens, and legs are spiny.

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).

In late summer and fall, woodland hikers can count on walking into the arrowhead spider's web. These webs are delicate circles that help the spider snare tiny flying insects.

Missouri has three species of spiny orbweavers in genus Micrathena. The webs of these woodland spiders are often run into by hikers!
