The Norfolk Moth Survey has just published its latest newsletter at http://www.norfolkmoths.co.uk/newsletters/84.pdf
I have put together a short article on Phalonidia udana and P. manniana with a comparison plate for reference.
I have dissected several of this duo and most are turning out P. manniana. So far in Norfolk P. udana seems confined to The Broads but further work over the next few years will reveal its true status.
Neil Sherman kindly sent me some from the golf course in Ipswich and from Redgrave Fen but again, all were P. manniana.
If anyone wants to save me any from next season feel free (Paul/Brian).
Best Wishes
Jon Clifton
The single specimen I took last year is a clear Phalonidia manniana on wing markings alone without resource to a dissection.
