As a result of surveying a calcareous flush in Great Close Mire Field, Malham Yorkshire (SD/90955 65676) on the 18th of June 2006 a single young specimen of a sinistral Euconulus alderi (Gray, 1840) was subsequently found amongst the 103 specimens of all ages found at the 23 sites investigated. The specimen, which had been alive when collected, had unfortunately died as a result of dehydration before it was extracted from the dried sample.
