Field Guide

Horntails look a lot like wasps but have a taillike spine that projects from the tip of the abdomen. Their cylindrical bodies also lack the narrow waist so common in wasps.

Moth flies look like tiny, hairy moths. People usually notice them perching next to sinks in the bathroom or kitchen. When disturbed, they usually don't fly very far before landing again, for they are weak fliers.

Hackberry psyllids are a genus of tiny, planthopper-like bugs. As larvae, they develop within the leaves, twigs, buds, or bark of hackberry trees. The trees form warty galls in response to their presence. In the fall, tiny adult hackberry psyllids cling to window screens.

True velvet mites: You’ve probably seen these small, velvety, bright red mites creeping around on rocks, plant containers, tree trunks, or on the ground, especially after a rain. Be not afraid! They are harmless — to people.

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.

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.
