Field Guide

House crickets are probably native to Eurasia but are found nearly worldwide, having traveled the globe with people. Unlike most other field crickets in our area, they are tan and brown instead of glossy black.

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.

The citrus flatid planthopper has a waxy coating and can look gray or tan. It eats a wide variety of plants.

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.

The spiny assassin bug is one of nearly 200 species of assassin bugs in North America. It walks, hops, and flies to capture its insect prey.

The pale green assassin bug, Zelus luridus, is one of nearly 200 species of assassin bugs in North America. Like other assassin bugs, it is a predator that captures and eats other insects.

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.
