Redknee, sorry for the long reply. Couldnt rememeber their name so had no hope in using google! hahaha. But its come back to me! Euscorpius flavicaudis is the scorpion in the UK. teeny and lives in mostly brick walls, old and crumbling.
Ive even looked in our house brick walls in HOPES because its old horrible bricks but...no. No resident scorpions!
They are mostly in dockland area too! and havent spread! so they are only in certain parts! like Cornwall and I havent been there for years...when I go...if I go again...im getting me a black light and im searching!
