Two Agonopterix moths from last night. The top I think is arenella and the bottom
looks like yeatiana, although this seems unlikely as it appears to mainly be a coastal species. Any help appreciated.....
And this was trapped at North Leigh Common, which has a lot of birch trees so I presume is Heringocrania unimaculella.
Hi Nic,
ReplyDeleteThe first Agonopterix is definitely arenella. I suspect the second will be heracliana but if you are trying to claim yeatiana I think it would need dissection. Yeatiana has not been recorded in Bucks and there are only about four records for Berks. While it is known from Oxon, I suspect it will be similarly rare.
Your Eriocrania is definitely one of the birch feeders but I'd be very cautious about getting it to species. As you say, unimaculella is a possibility (see what Martin says). In May it would be worth checking for leaf-mines on the birch at North Leigh Common because there are likely to be several species present and most can be told apart by looking closely at the larvae.
Thanks Dave. Very much appreciate that.
DeleteI'll check out those birch leaves ....
Regards,
Nic.
