A couple more mines from my foray into Dibbinsdale LNR on Thursday. The challenge with this was to identify the tree - it took me longer than I care to admit to work out it was Hazel, not Alder or Hornbeam.
The first two I think are Stigmella microtheriella. My logic for going for this rather that S. floslactella is that the mine and frass line look thinner - is this correct?
I think the next one is Parornix devoniella, based on the fact that the leaf is folded upwards. There's also a blotch mine on this leaf that I can't identify.
Finally a different blotch mine, which I think is another Parornix devoniella, at an earlier stage.
Only 3 more trees to go! (Beech, Hawthorn and Oak).
Cheers
Paul

Re: Leaf mines for ID help - Hazel
Hi Paul
I still find the Stigmella mines on Hazel difficult to resolve, especially these from the summer generation. The autumn generation tend to be easier, with Stigmella microtheriella showing a thin black frass line at the start of the mine, with clear margins, compared to the brown frass line of Stigmella floslactella, which fills the early mine, without any clear margins. I looked at several yesterday similar to yours and was unable to decide.
Parornix devoniella is correct
