Thanks Sue, I have tried looking at the various images on the web, but they don't seem to match very well. As you can see, I have a Holly Blue to find, which I know is predominantly
blue (would you believe

), but the two remaining ones are nothing like it

Agrias Lugens has the most blue of the six designs, but I'm pretty sure this one is correct.
Guess I'll have to wait for a wildlife expert to drop by. Kev, perhaps?
