Brown recluse spider (likely)

Dry, dark, undisturbed areas such as closets, boxes, sheds, basements, and woodpiles, mainly in the south-central and Midwestern United States.

Predatory; eats insects and other small arthropods, usually subduing prey with venom and consuming it externally.

Nocturnal and nonaggressive, typically avoiding people; it builds a small, irregular web for shelter rather than prey capture and may wander indoors. Identification from this image alone is not definitive.

Bites are uncommon but can cause localized tissue damage and, rarely, systemic illness; avoid handling and seek medical advice for a suspected bite. It benefits ecosystems by reducing household and outdoor insect pests.
