Assassin bug nymph (likely a wheel bug nymph)

Gardens, wooded areas, and buildings’ sunny exterior walls in eastern North America.

Predatory; pierces and feeds on other insects, including caterpillars and beetles.

Nymphs are often reddish-orange and dark, with long legs and a narrow head. They develop through several molts into adults and may hunt on walls or vegetation.

Useful natural pest control. It can deliver a painful defensive bite if handled; the bite is not medically significant for most people.
