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 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.

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

The diamondback spittlebug is common in weedy areas. The larvae live protected in spitty masses of foam. The adults are drab and well camouflaged, so few people notice them.
