Hello,
Terana caerulea is a decidetly atlantic and somewhat thermophilic species – where is the best region for this species in Britain if not Glamorgan
I have seen it as a common species at the atlantic cost of France north of Bordeaux up to La-Roche-sur-Yon, and I suppose it is common everywhere at the french atlantic cost.
On the other hand we have never had a finding in Thuringia (except a dubiose dataset), which is one of the warmest areas in Germany, but in the east and quite continental.
best regards,
Andreas
