Species account from Moths of Glamorgan (Gilmore, Slade & Stewart, 2009):
Another oak feeder, this one also starting out in a gallery that then leads to a blotch, but differs from the previous species by having a slit in the lower epidermis to allow frass to ejected from the mine, and the gallery part of the mine is less obvious. Only recorded once in Glamorgan to date: Melincwrt, 09.xi.1997, (BS & SJS).
