So far this season at least six aberrant specimens (rare colour forms) have been seen and photographed in Fermyn Woods, including one female. Two individuals were photographed today (see forthcoming post by Neil Hulme).
Below are photos of what I take to be the same specimen of what is probably ab lugenda, the first two photos taken on Tues 24th by Phil Beard and the bottom one by Rev John Woolmer on Thurs 26th. Our congrats and thanks to Phil and John.
Incidentally, I have long suspected that Purple Emperor aberrations (or variations) are proportionally no rarer than White Admiral aberrations, it's just that we see far more of the latter!
