Field Guide

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.

Mature female starbellied orbweavers spin wheel-shaped webs in prairies and other open, sunny habitats. The abdomen is decorated with a crown of spines and usually has a star pattern on the back.

Female and male five-banded thynnid wasps look quite different. Both are banded with black and yellow, but the females are large and heavy-looking, while the males, often seen in groups, are much skinnier and have a scythe-shaped false stinger on the hind end.

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.

Cockroaches well-known: they are flattened, small, brown or black, often shiny insects that can hide in tight crevices and lack specialized appendages. Recently, termites have been included in their order.

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 delta flower scarab got its name from the bright yellow triangle on its pronotum. It commonly visits a variety of flowers in prairies, old fields, and other open areas.
