Field Guide

Not all Missouri lady beetles are red with black spots. The four-spotted lady beetle reverses the pattern.

The seven-spotted lady beetle is native to Eurasia and was introduced to our continent to combat aphid pests. It is now well established in North America.

The ninebark calligraphy beetle is one of nearly 40 North American calligraphy beetles, named for the scrawly markings on their backs. Most calligraphy beetles require particular host plants.

The elm borer is a longhorned beetle whose larvae bore galleries under the bark of elm trees. The orangish markings on the adults are distinctive.

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.

Rove beetles usually have very short wing covers, so several of their hind abdominal segments are exposed. Typically fast movers, they often flip up their abdomen tips when frightened. This is a huge family of beetles.

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.
