Field Guide

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.

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.

The orange assassin bug, Pselliopus barberi, is about ½ inch long and is one of our most attractive non-butterfly insects. They overwinter in groups as adults under loose bark.

Members of the pygmy grasshopper family are small and have a distinctively elongated pronotum — this plate, which only covers the shoulders of most other grasshoppers, extends back to cover the abdomen in this family. Most live along streams and in other wet habitats.

Tumblebugs in genus Canthon are usually seen on, near, and beneath poop. They are sometimes seen rolling dung balls away from the original heap, heads down and pushing the ball backward with their hind legs.

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.

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.
