Habitat
In general, land snails have certain limitations in regards to their habitat that must be moist, protect them from predators and the elements, and have enough food that is easily accessible that includes calcium (Nekola, 2000).
Generallly this species can be found within tropical and subtropical America, and ranges from the temperate weather of the east. They are not abundant in the north as much, for they have only been spotted south of Ontario (Grimm,et al., 2009).
In Michigan, Guppya sterkii is found along the western facing cliffs and bedrock made of limestone or calcium, as well as within the Mesic Northern Forest ("Guppya sterkii", 2007). The Guppya sterkii within Wisconsin, however, can be found among the leaf litter of wooded hillsides and within ravines ("Brilliant Granule (Guppya sterkii)", 2009). The Brilliant Granule has also been found in other regions of the Midwest such as the cliffs within Iowa's that supply the necessary calcium for snails, along with the talus slopes of Iowa and Wisconsin. These snails were also found as far as the Appalachian Mountains ("Guppya sterkii", 2007).
While doing research on Guppya sterkii, Nekola encountered four regions that this taxon resided. Near the Green Bay area they were found within areas such as rock outcroppings and forests (2004). This helps to illustrate that the Brilliant Granule can be found mostly in the Door and Garden Peninsulas even as they are characteristic of the southeastern US (Nekola, 2004).
Guppya sterkii was also unquestionably shown to prefer duff soil for their habitat (Nekola, 2003).
