I had a couple of Chestnuts in my trap last night at Beenham Berks. The first is a Chestnut but the second was very dark ( I realise that colour isn't everything) and I believe that the wing shape is sufficiently different to suggest Dark Chestnut. What do people think?
Hi Derek,
ReplyDeleteThe top one is certainly a Chestnut, as you say. I think the bottom one is most likely a Dark Chestnut as there does seem to be a fairly sharp 90 degree angle at the apex between the costa and termen.
