Eggfly again

I blipped this species on 25 April, and included there a link to a Wikipedia page.  Since then, as we've moved into our mild winter, numbers seem to have increased. The Eggfly is common in tropical and sub-tropical Australia, especially in coastal areas. I read that in New Zealand it's called Blue Moon butterfly, after the iridescent circular blue patch in the upper wing of the male. This is the under wing, I think of a female. But I'm willing to be corrected.

Incidentally, I've inverted the picture. She was hanging upside down below the branch, of a small palm in my garden.
