Some slight movement caught my eye. Turned out to be a pair of pale blue butterflies doing a circular mating dance.

I love the rich detail, the false eyespots and antennae, the shaggy wing edges, the powerful little feet, and the exquisite clumsiness of the whole affair.

After some investigation, I believe this is Lampides boeticus, the "Long-tailed Pea-Blue Butterfly".
