Wheel Bug

Natural Habitat

Common in gardens, orchards, and woodlands across North America; often seen on trees, shrubs, and flowers.

Diet & Feeding

Carnivorous predator; feeds on insects such as caterpillars, beetles, aphids, and bees by injecting lethal saliva into its prey.

Behavior Patterns

Diurnal predator known for its characteristic 'cog-wheel' or 'crest' on its thorax. They are slow-moving and generally solitary, using a long proboscis to hunt and feed. They undergo a simple metamorphosis with one generation per year.

Risks & Benefits

Extremely beneficial to ecosystems and gardens as a natural pest controller. However, they can deliver an extremely painful, though not medically significant, bite if handled or provoked, known to feel worse than a hornet sting.
