Here in northeast Florida Polygyra cereolus is by far the most common terrestrial species and can be found in massive numbers at some locations. Because of this, the species serves as an easy source of food for the carnivorous Euglandina rosea (Férussac, 1821) [Rosy Wolfsnail]. Pictured below is a 57 mm. Euglandina rosea collected in the roadside swale in far western St. Johns County, Florida on 11/11/2013 and its gut contents, which consisted of eight Polygyra to include both P. cereolus [Southern Flatcoil] and P. septemvolva Say, 1818 [Florida Flatcoil]. At least two other snails were present in the gut but were so far along in the digestive process that they could not be positively identified,
