Hi David, some features of this moth do fit E. lacustrata, but because its markings are not very distinct especially in the sub-terminal area I would not be able to classify it as definitely this species. The outer part of the wing contains a white crossline (only clearly seen on the left side here) and sub-terminal white markings that in some Eudonia/Scoparia species can add up to a large white 'X' (in E. mercurella, for instance). In E. lacustrata the two outer 'arms' of the 'X' are usually separated by a black patch, so that the white 'X' is incomplete. However, in your moth this feature cannot be clearly seen, hence my uncertainty.
