In Britain this species is sometimes called the “Cliveden snail”, as in 2004 a very small colony was found to have been living on the estate at Cliveden House, a large stately home in Buckinghamshire, England.
Individuals of the species had been living on an Italian balustrade which was imported to Britain in the late 19th century, and have survived at the estate for over a century before they were discovered there. Other introduced populations of P. papillaris can be found across South East England.
