Field Guide

Tachinid flies are one of the largest families of flies. They are parasitic flies whose larvae are parasitoids of other insects. They look a lot like house flies, blow or bottle flies, wasps, or bees. Many are very bristly.

The Georgia mason is one of several species of mason bees in Missouri. Like other megachilid bees, it is a native solitary bee that carries pollen in a special clump of hairs on the underside of the abdomen.

The Carolina grasshopper is frequently seen in dusty, open habitats like dirt roads and vacant lots. Its yellow-bordered, black hindwings make it look like a mourning cloak butterfly.

The lichen grasshopper sticks to sunny, rocky areas, such as the many rocky glades and hilltops in the Ozarks, where lichens are plentiful. It is perfectly camouflaged there.

Andrenid bees, also called mining bees, are solitary ground-nesters. Most are specialist pollinators whose life cycle is timed to correspond precisely to the blooming of specific flowers.

Ommatius robber flies are medium-sized robber flies with distinctively branching antennae. There are about four of five species that might occur in Missouri.

Longhorn bees are named for their long antennae, which make these fuzzy, medium-sized bees look rather cute. Many have yellow faces.

The green robber fly is one of several species of robber flies called giant robber flies or bee killers. They are indeed large, with distinctive yellow and dark stripes on the abdomen and iridescent green eyes.

The yellowjacket hover fly, or Virginia flower fly, is a completely harmless mimic of yellowjackets. No more dangerous than a housefly, it buzzes around and seems aggressive.

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.
