A flurry of micros - help needed

My garden trap attracted 11 moths last night - no doubt due to the much milder temperature. Of these, only 3 were macros (1 Pale Brindled Beauty, 1 Spring Usher and 1 Early Moth). The remaining 8 were all micros, so I had to blow the dust off the micro-moth guide book!
The first one below I am certain is Agonopterix alstromeriana.

Then there were 6 micros that all looked fairly identical in appearance, and which I have recorded as Acleris ferrugana/notana. Here is one below (fw 7mm).

The final micro, however, has got me completely stumped, so any help much appreciated. The forewing measures 9mm, and I have posted both a top view and a side view.

  1. Hello Steve, Agonopterix alstromeriana and Acleris ferrugana/notana are both correct (if you haven't already done so it would be worth keeping one for a genitalia check sometime - ferrugana is by far the more likely locally). The third moth is Ypsolopha ustella which is a highly variable species but is really the only one from that family likely to be tempted out of hibernation at this time of year.

    1. Many thanks Dave. I have looked at various pictures of Y. ustella and it certainly is a very variable species - no wonder I was struggling to identify it.
