Mullein Wave (Scopula marginepunctata)

It also matches the specimen depicted on EOL and the one on Wikipedia*.

With much respect Chris I really do think this is the Mullein Wave.

PS I was sure I put the link in UK Moths, I have now. :)

* A perfect match....

re Idaea dimidiata

and Scopula marginepunctata, total confusion on the web. I do not have a key so I assumed that a key difference between the 2 based on the 3 sites I first looked at, (the above), was the black spotted border to the wings. The image on UK moths depicting Idaea dimidiata has no black spots around the wings. So does one have them and the other not, I ask the question...?

Idaea dimidiata

Idaea dimidiata certainly has black spots around the edges of the wings.

Hi Mick, I must have just looked at dozens of images of a Mullein Wave and I'm just not seeing what you are seeing, perhaps it's my aged eyes or something. There seems quite a difference between this specimen and those on your link to UK Moths, again perhaps it's me. I'm sticking to my original ID, lets hope an expert can set the record straight because I'm far far far from that. Regards Chris

one for the experts, and if they both have the black spotted wing margins then its one for the microscope too.

I guess you are doing the mothnight too..? It has inspired me to look harder for ID's, but the norm is not even the experts agree at times.
