Blue Butterfly

The wild pears drop at irregular intervals like a volley of shots onto the tin roof of an unused kennel. The fermenting fruit have attracted wasps, bees and a few butterflies to dine. I waited for a long time to shoot this one with open wings. There were some other more obliging butterflies sipping the juice, perhaps already under its influence, but I tried to shoot this one since I hadn't noticed it before. Perhaps some very kind person out there will help us identify it?
