I have recently written an article for Dispar.org regarding the extinction of the Mazarine Blue butterfly in Great Britain:
<a href="http://www.dispar.org/reference.php?id=100" rel="nofollow">dispar</a>
I have elaborated upon changes in distribution and flight period (illustrated appropriately) in order to provide a clearer understanding into the possible reasons behind, and pace of, the butterfly's demise which some of you might be interested in reading.
Let me know your thoughts!
