I am always being rude about 'yellow underwing' moths, so today I shall make amends. They are very trying, because they come to the trap in such large numbers. I would never be a good scientist, because such a mass of data overwhelms and, I'm afraid, bores me. A Darwin or Wallace would work patiently through them, delighted to have so much evidence. And without a lot of evidence, scientific theories can unravel. It is interesting how many concepts, especially those seized upon by journalists, turn out to be based on very small samples.

Interesting on the blue/green subject, as I was reading your post, I thought, well what about the Forester Moth? and then I realised that that's a day flying moth, so rather more akin to a butterfly. Hmm.
Hi W (I'm going to try to do my Dabbler post today, thanks to you btw) I think it must be to do with light. I did a Google last time I mentioned it but didn't get very far. I must check out my E B Ford book on moths as he has quite a lot on colouring (although I think I have done this before and come away still unsure about blue)
All v best

well as a definate amateur I would hazard a guess similar to yours - as butterflies and day flying moths see predominantly in the ultraviolet spectrum that the blue colouring is for courtship display to other butterflies rather than as explicit protection from birds and other predators, (although I had heard somewhere that owls are the only birds that see blue), but Im not sure if this is really true
everyone is really looking forward to your piece!
