Habitat
The habitat of this species is underground, quite some distance below the surface. It is more common in soils with a high level of calcium.[4]
Because of its subterranean habitat, this species is often found only as an empty shell, in such places as mole hills, ant hills, or in flood debris of rivers.
Distribution
Distribution of this species is central European and southern European.[5]
The United States (in Pennsylvania and in Florida,[13] in Maryland since 1959,[14] in Virginia since 2006,[15] in California, in New Jersey and in New Mexicoà[16]
