Family Pupillidae - Pupillid Snails
The family Pupillidae once was considered to include these genera: Columella, Gastrocopta, Pupilla, Pupoides, and Vertigo. Today only Pupilla and Pupoides remain, with the other three placed into the Family Vertiginidae (Hotopp et al 2013). All of these are small taller-than-wide, pupa-shaped snails.- more like a cocoon. Some taper, more or less, at the apex. Apertural teeth vary greatly and the lip is usually but not always reflected (Columella for example).
Only 2 Pupillidae are found in Indiana - the more common White-lip Dagger and the rare Widespread Column Snail.
