I was interested in the note by David Notton of the Natural History Museum and the comments of Tom Cadman, Species Policy Officer, Wildlife Species Conservation Division of Defra on the occurrence of Eobania vermiculata on Lewisham Railway Station. Mollusc World Number 11 page 6 July 2006.
A live adult specimen of this species was found attached to a tree purchased from Palmer Plants Nurseries, Calverley Lane, Pudsey near Leeds, Grid Ref. SE44/ 2136, in July 2003.
Subsequent enquires at the Garden Centre established the fact that deliveries of trees from the Mediterranean area took place twice a year, with lorry pickups from Italy, Southern France and Spain. As Eobania vermiculata occurs in all three of these countries, I was unable to establish which of these the specimen originated from. I had hoped to make subsequent visits to the nurseries to examine trees soon after they arrived at the garden centre but other factors put the issue out of my mind until I noted the article by David Notton.
