Whilst visiting Fontmell Down on 3/08/18 Mark came across this Chalkhill Blue, aberration. He tells us he feels sure he saw a similar one there a couple of years ago. There are many aberrations of  various species of butterflies and more information can be found on this link.    http://www.ukbutterflies.co.uk/aberrations.php
