Field Guide

The eyed click beetle is only one of about 1,000 species of click beetles in North America. Most of the others are drab in comparison.

The locust borer is a longhorned beetle whose larvae tunnel into the trunks of black locust. The colorful black and yellow adults are often seen in late summer as they feed on the pollen of goldenrod and other flowers.

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

The European hornet is a large, nonnative hornet that was introduced to New York in the mid-1800s. They now occur across most of the eastern United States, including Missouri. People may misidentify them as the highly publicized, so-called murder hornets.

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.

Earthworms are familiar to just about everyone who digs in the soil. They play a major role in the nutrient cycling and structure of soils. There are many species. The most familiar ones in Missouri are nonnative.

Darkling beetles are a very large family of beetles. Most are dull black or brown, crawl on the ground, and are scavengers. Many of them resemble what you might call a “base-model” beetle.

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.

The common meadow katydid is aptly named: it is well-known and widespread in the eastern United States. Listen for its distinctive call — like a pulsating circular lawn sprinkler ratcheting around — in midsummer to the first hard frost.
