Acleris effractana?

A few weeks ago Chris caught two Acleris - one obvious A emargana and one probable A effractana.  The latter would have been new to Carms, but needed gen det for confirmation.  I caught another probable A effractana here at Cnwc y Llwyn last night.  It's rather plain-winged and has a shallow 'scallop', and I'm sorry to say it's now residing in the freezer so it can be dissected later.  The only problem is that I'm not sure what I'm meant to look for to separate the two species!

  1. Sam, UKmoths website description of A. effractana gives a link to where you will find an illustration of the male genitalia. Apparently the socii are slightly longer than those of A. emargana. Seems a bit flimsy to me, but that's as far as I got. I don't know what you'd do if it's a female! Maybe there's more info to be had on-line particularly from northern areas where A. effractana seems to be more common.
