Further to Sam's comments which suggest the possible occurrence of
Acleris effractana hereabouts I thought it might be helpful to show photos of this moth together with two recent examples of
A. emargana to illustrate the apparent difference
. Sadly neither species turned up last night, but
Acleris laterana was amongst a modest 22 species recorded on a mild, dry night. Amongst the catch were two more Brindled Greens and the first Autumnal Rustic of the season.
Acleris emargana 1
Acleris effractana?
Acleris emargana 2
The photo of effractana certainly looks very different from any of the emargana I've seen in South Wales - must keen an eye out for it.

Acleris emargana is relatively easy to beat by day from willows, so it may be worth us beating a few willows in upland Carms in the hope of A effractana. I wonder if you'll beat us to a conclusive record in Glamorgan, George.
ReplyDeleteThere's a willow/sallow copse bordering our property, which may account for the presence of this species. It's too wet to go beating just now though!
