Apologies....

P. S. Just had a reply from our butterfly expert, these are Green-underside Blues, Glaucopsyche Alexis.

I am not obsessed with butterfly mating, honest. It is just that I haven't consciously seen these before. I was on one of our butterfly fields trying to complete the set of Common Blues with a classic male (got one.... in extras) when I almost knocked these off their perch! They are so different and delicate, I had to post them.

Huge thanks for the many gifts for yesterday's butterfly pairing.
