Field Guide

The six-spotted tiger beetle is probably the most familiar tiger beetle in Missouri. It’s most often seen in spring, as it darts in and out of trails just ahead of hikers.

The pronghorn clubtail is one of several members of its genus in our area that are generally difficult to identify. Like other dragonflies, it is an aerial predator that hunts insects on the wing.

The fork-tailed bush katydid reaches about 1¾ inches long. It is usually leafy green and is most common in bushes, thickets, and other shrubby areas. It is most active after dusk. The call is a simple "tsip!" given every few seconds.

The longlegged flies are a large, diverse fly family. They often have eye-catching metallic green, copper, bronze, or blue bodies and long legs. Their delicate wings are often clear and look iridescent in bright light, but many species have dark marks near the wing tips.

Mantidflies look like a cross between a lacewing insect and a praying mantis. They are small, delicate creatures with intricately veined wings, but the front half looks like a mantid, complete with raptorial forelegs.

Plant bugs, or mirids, are a huge family of true bugs. They are often overlooked — except by gardeners and farmers. Most mirids eat plants, and some are agricultural pests. As a group, they’re an important food source for birds and other insectivores.

About six species of bird grasshoppers occur in Missouri. Most are attractively marked, large insects that gracefully fly from danger, almost like birds.

The common claybank tiger beetle, or green-margined tiger beetle, occurs on dirt clay soils in open areas in spring and, less abundantly, in late summer. Color varies from red to purple to green. The outer shell edges are often edged with shiny green.

The American bird grasshopper is a large grasshopper with ornate markings. It is a good flier that floats upward into trees. Note the pale stripe running down the back.

Katydids are a family of insects that may also be called longhorned grasshoppers, because of their super-long antennae. Many resemble green leaves. Others are brown. Members of some species may be bright pink or yellow.
