Assassin bug (likely wheel bug nymph)

Gardens, forests, fields, and other vegetated areas across much of eastern and central North America.

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

Usually solitary and ambush-oriented, resting on vegetation while hunting. Nymphs develop through several molts before becoming winged adults; the pictured insect may also be a different green reduviid nymph.

Beneficial for natural pest control. It can deliver a painful defensive bite if handled, but is not considered medically dangerous.
