Field Guide

Many apid bees are well-known. This family includes the familiar honeybee, bumblebees, and carpenter bees, plus many that are less well-known. With few exceptions, most of Missouri's apid bees are native, solitary species.

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.

The American carrion beetle has a yellow pronotum with a big black spot in the middle. Adults of this species of silphid beetle eat fly maggots, plus some carrion. In flight, they seem like bumblebees.

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 openfield orbweaver is a common nocturnal orb-weaving spider in Missouri.

The marbled orbweaver is sometimes called the “pumpkin spider” because its rounded abdomen is sometimes bright orange. The color and markings can vary greatly.

Armored harvestmen have spines on their fingerlike mouthparts (pedipalps). Unlike other harvestmen, members of this suborder of so-called daddy longlegs do not usually have long legs.
