Wheel bug (assassin bug)

Woodlands, gardens, and yards across much of North America; often found on vegetation and around buildings.

Predatory; pierces caterpillars, beetles, and other insects with its beak and sucks out their fluids.

Usually solitary and slow-moving; adults have a distinctive semicircular, toothed crest on the thorax. They can fly and overwinter as eggs.

Useful predator of garden pests. It can deliver a painful defensive bite if handled, but is not medically dangerous.
