Eudonia lacustrata?

 Hi there,

Using the Berks micro book, I think I have sufficient features of lacustrata to separate this specimen from mercurella.

Confirmation welcome!

Many thanks

David

  1. 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.
