Field Guide

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.

Pseudoscorpions are unusual little arachnids. They look something like tiny scorpions but with a rounded (and nonvenomous) hind end. They're common but often overlooked.

Millipedes, which have two pairs of legs per body segment, are harmless detritus-eaters, move slowly, and curl up defensively when harassed.

Be careful when approaching northern two-striped walkingsticks: They can squirt an acrid fluid at you. Musk mare, devil’s riding horse, and prairie alligator are all names for this remarkable stick insect.

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).

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 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.
