Hi Gary - the spreadsheet here is used by the BC European Interest Group:
http://www.bc-eig.org.uk/species.html
You might find some species missing, and this is because they've been "lumped" with other species in most cases. When we did the analysis for the
Butterflies of Europe app, we found the following "missing":
Cupido carswelli - Carswell's Little Blue
Maculinea rebeli - Mountain Alcon Blue
Agrodiaetus ainsae - Forster's Furry Blue
Agrodiaetus agenjoi - Agenjo's Anomalous Blue
Lysandra philippi - Macedonian Chalk-hill Blue
Polyommatus andronicus - Phalakron Blue
Polyommatus eroides - False Eros Blue
Polyommatus menelaos - Taygetos Blue
Vanessa indica - Indian Red Admiral
Coenonympha elbana - Elban Heath
Coenonympha darwiniana - Darwin's Heath
You'll notice that the species aren't in taxonomic order - and so we used (to a large extent) the order in Tolman and Lewington.
Cheers,
- Pete
