Wheel Bugs Roll On

Adult and nymphal wheel bugs are relatively common predators that can be found on trees and shrubs in late summer. Adults have cog-like wheels on their backs. Both adults and nymphs are predators that seize their victims with long grasping front legs and jab them with stout beaks. These members of the assassin bug family feed on a variety of caterpillars, bugs, beetles, and bees. The bite of an adult can be more painful than a bee sting so they should be left alone.
