I think those very obvious pale triangles across the face make it N uliginosus , but the face doesn't seem quite projecting enough - may be the angle of the shot.

Quite an interesting record if it is this species. I have just sent in my records to my County Recorder and he told me that they are usually found on Scentless Mayweed (which is where my specimen was).

I'll double check Stubbs when I get home unless someone gives you a definitive answer re species in the meantime.
