Wheel bug nymph (likely)

Trees, shrubs, gardens, and buildings near vegetation across much of eastern and central North America.

Predatory; it pierces caterpillars, beetles, aphids, and other insects with a stout beak, then liquefies and drinks their tissues.

Mostly solitary and active from spring through autumn. Immatures develop through several wingless stages; adults have a distinctive cogwheel-like thoracic crest and may fly or climb on walls.

Beneficial natural pest control. It is not dangerous unless handled, but can deliver a painful defensive bite comparable to a bee sting.
