Field Guide

Like damselflies, dragonflies have long bodies, two pairs of long, membranous, finely veined wings, and predaceous aquatic larvae. Dragonflies typically hold their wings stretched outward, horizontally.

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 heptagonal orbweaver, Gea heptagon, builds its circular webs in vegetation only a few feet off the ground. When disturbed, it drops instantly to the ground below and turns a drab brown.

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.

An unwanted arrival from Asia that's now living in parts of the United States, the Asian longhorned beetle could destroy millions of acres of American hardwoods. Report any sightings immediately.

Silverfish are known worldwide, since they commonly live in our homes. There are a number of species in this family of insects, including the common silverfish and the firebrat.

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.

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 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.
