Field Guide

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.

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.

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

Walkingsticks are long, slender insects that are perfectly camouflaged to look like brown or green twigs. Most species are tropical, but some types are found in Missouri.

The brown recluse is a spider whose venomous bite may be medically significant to humans, though a bite is almost never fatal. Brown recluses are most commonly encountered in houses, where they occupy little-used drawers, closets, and other small hiding spaces.

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.

The funnel-shaped web of grass spiders is more often noticed than the spider itself. It is sheetlike, usually positioned horizontally, with a funnel leading downward to a shelter (a rock crevice or dense vegetation) where the spider hides, waiting for prey.
