Duffryn

 Saw a couple of leaf mines on Hazel today.  The first one I believe may be Stigmella microtheriella.  There is not a lot of frass in the mine so I reckon it is microtheriella rather than floslactella.














The second mine (below) I cannot see a promising match for.  Any ideas?  Apologies for the quality of the photos and the leaves being somewhat dessicated!

    It can be hard to tell Stigmella microtheriella / floslactella from old mines when the frass has dried up, so I'm not sure you'll be able to record that one with certainty.

    The second one is Phyllonorycter coryli - the big upper surface blotches are distinctive. See:

    Thanks George! I did check the fresh leaf for frass before taking it home so I think S microtheriella is a safe bet.

    Note also that it's the frass in the first third of the mine you need to look at, as both species show clear margins therafter.
