Orb-weaver spider (likely a barn orb-weaver)

Wooded areas, barns, porches, eaves, and other structures where it can anchor a web. It is commonly found near outdoor lights that attract flying insects.

A predator of flies, moths, mosquitoes, beetles, and other small arthropods. It captures prey in a sticky orb web, then immobilizes it with venom and consumes it externally.

Usually nocturnal, building or repairing its orb web at night and hiding nearby during the day. Adults are most noticeable in late summer and fall; egg sacs overwinter and spiderlings emerge in spring.

Generally harmless to people and not aggressive; bites are rare and usually cause only mild, localized symptoms. It is beneficial because it removes many nuisance and pest insects.
