General comments: The mapped records are those examples of long, narrow mines with linear central frass and unequivocally clear margins on bramble, as well as those on Raspberry leaves, to which the bulk of the mapped records relate. The foodplant name should always accompany submitted reports of mines so that, if we eventually discover that more than one species is involved, we will be able to separate out the records for each.
Mine: Moth needs to be reared and, in some cases, possibly dissected.
