Have you ticked Delplanqueia dilutella? Many people probably ticked it under the name Pempeliella dilutella but since then it has been found that there are two species in Britain; D. dilutella and D. inscriptella. Early results suggest that the latter is the commoner species, at least in England. I am not actually aware of any confirmed records of dilutella in England as yet. I suspect many people who currently have this species on their list need to hit the delete button (or dissect their specimens if they have any).
