Leptidea sinapis...I think

A wood white (?) of which there were quite a few at Northington Grange, which Mr DawnAgain and I popped over to visit this morning. I'd been there on my own once before and, having passed it again on my way back from Andover the other day, I had been reminded that Mr DA would probably quite like it - which he did. It's a crazy place, really: a 17th century red brick house clad in cement to resemble the Temple of Hephaestus in Athens. One rich 19th century man's act of Greek Revival folly in the most delightful setting.
