Field Guide

Bot flies are chunky, beelike flies usually with rounded heads. Adults are not commonly seen. The larvae are short, pudgy, segmented grubs that live as parasites in the tissues of animals. Those that live just under the skin often form a bulge. Some types live in the nasal or throat cavities of deer.

Whitebanded fishing spiders are often seen on tree trunks, walls, or other vertical surfaces, sometimes far from water. The coloration and markings can vary, but many individuals have an olive-green cast that helps them blend in with mosses and lichens. Note the bristly legs.

The white micrathena has 2 short pairs of tubercles and a white abdomen with a few distinct black blotches on the upper side. In an odd way, it looks like it's wearing a turban. This is one of three Missouri species of micrathenas, also called spiny orbweavers.

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 longlegged flies are a large, diverse fly family. They often have eye-catching metallic green, copper, bronze, or blue bodies and long legs. Their delicate wings are often clear and look iridescent in bright light, but many species have dark marks near the wing tips.

Millipedes in family Xystodesmidae often have bright colors that serve as a warning to potential predators that they may secrete foul or toxic substances.

The oblong-winged katydid is one of many species in the katydid family. Although it is usually green in most places, some populations made up of pink-form individuals.

Poecilopompilus spider wasps provision their nests with orbweaver spiders. They dig nest burrows into the ground and therefore prefer sandy or other workable substrates.

Spider wasps in genus Entypus are bluish black and usually have some amount of amber color on their dark, smoky wings. Some species have bright yellow antennae.
