Colias Alert!

Marie O’Shaughnessy photographed this sulphur at McIntyre reservoir yesterday, August 22.  There are evidently still a few Teasels in flower – enough to attract this butterfly.  I’d be glad of opinions (with reasons!) as to which species this is. With luck some butterflyers will visit the reservoir today and be able to see an upperside and see if there is any orange.
