Hi, Everyone!
There are indeed records of Arianta
arbustorum from North America. In the 1980's
my colleague, John Maunder, and I discovered
several colonies of A. arbustorum in the St.
John's, Newfoundland area. There were two
forms of this species. They were quite
common in some localities, and I would assume
that they are still there.
They were found in the city and around nearby
towns. We believe that they were probably
introduced.
St. John's is an old city, as North American
cities go, and a large proportion of the land
snail fauna there appears to have been
introduced, probably from Western Europe.
I hope this is helpful.
