More ID help please

A fairly disappointing catch last night despite the higher temperature. There were dozens of wasps and about 15 hornets which had eaten quite a bit of the catch judging by the debris in the bottom of the trap.
However, I would appreciate some advice on the following two moths.

I assume this is either Acleris emargana or A. effractana. From the pictures in the book it looks a bit more like the latter but is it possible to distinguish them from external features?

With the black marks on the leading edge I had wondered about Pale Mottled Willow for this one but can't see any white dots around the kidney mark.

  1. Hello Andy, not a moth I've knowingly seen but your picture does look as though it could be a candidate for effractana. However, as it says in the field guide, "examination of genitalia is required to confirm identification of A. effractana". If you've still got the moth it would be worth letting Martin Corley have a look at it.

    The other moth is indeed Pale Mottled Willow.

  2. Thank you. I'll get in touch with Martin as I do still have the moth.
