Araneus cavaticus, commonly known as the barn spider, is native to North America. It is primarily found throughout the United States and southern Canada.

The barn spider typically inhabits areas that are close to human settlements, such as barns, sheds, and other structures. These environments provide the spider with ample opportunities to build webs and capture prey. The climate in these areas can range from temperate to slightly humid, depending on the specific geographical location.

Araneus cavaticus occupies a niche where it acts as a predator of various insects. It builds orb-shaped webs to capture its prey, which includes flies, moths, and other small arthropods. This ecological role helps control insect populations in its habitat.
