There is one BSBI record of U. incisa in W Scotland, plus a lot of others (maybe not verified, I don't know) on NBNG scattered through England. The appearance on iSpot posts is because if you put in 'Nettle' to the English name, and click 'Get recommended', U. incisa and Scrub Nettle are inserted. I don't understand it either. Whenever I want to ID 'a red ant' the system insists it ought to be a 'Blue-eared Pheasant'. Technology is wonderful, but only up to a point!
