Chrysoteuchia culmella - Moth (no common name)

20mm wingspan - a grass moth.

Not a great shot I'm afraid, but since they are apparenty very jumpy creatures I decided that I probably wouldn't get another chance!
Because the gold of the moth doesn't react well with the light I put the 2 shots together so you could get a more complete view of the patterning - it's the angled lines that distinguish it.
As you can see - it was a windy day. even sitting on the inside of the window frame :)

What beautiful wings, Louise!

Those in the third photo look just like raw silk!:)

Are you sure it isn't flashing you on the second photo Louise?

Aah, yes, of course - it's the Mooning Moth :-rolling
