This species is a terrestrial snail meaning it lives on land and not in aquatic environments. They can be found in creeks and valleys (Discover Life, 2012). On steep slopes under rocks is another area Patera indianorum can be located (Pilsbry, 1940). Other areas this snail can be found include on top of ground cover, in deep leaf litter, and under decaying logs (Perez, 2008). This snail tends to live in habitats that are moist and wooded (Discover Life, 2012). Since calcium is an important part of the snail's life and is used to regulate body functions and create the shell, this species tends to live in soil with high calcium levels (Illinois Department of Natural Resources, 2012). In contrast, the snail is affected when acid rain is present due to the lower calcium level in the soil (Illinois Department of Natural Resources).
