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.

Scoliid wasps are a family of beetle hunters. Large, rather hairy wasps, some are handsomely colored. The female digs in soil, finds a scarab beetle grub, and lays an egg on it.

The female black giant ichneumon wasp deposits her eggs through wood. The larvae eat the grubs of wood-boring insects.

There are 10 species of spider wasps in genus Auplopus in North America north of Mexico. They often snip off the legs of the spiders they capture, which makes them easier to move around.

The eastern stizus is a large, solitary wasp that is often misidentified as the better-known eastern cicada-killer wasp. The markings are slightly different, however, and the eastern stizus female hunts katydids, not cicadas.

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.

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.

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.
