Who wouldn't be?

Happy with this shot, I mean.  I can remember a time some years ago when everyone would be whooping with delight at getting an image of a Caper White (Belenois java teutonia).  This year they are so common as to be almost ho-hum.

Aren't they lovely though - a lot of people confuse them with the Common White, which is rather smaller, and doesn't have that beautiful back wing.

Just in case you are interested, here's the entry on the Butterfly Conservation SA website:  "This butterfly is a migrant to South Australia.  Every few years there are immense migratory flights of adult butterflies sometimes with thousands of individuals, commencing in the north of the state and moving south to Adelaide, Mount Gambier and Kangaroo Island.  Locally common in breeding areas and during southern migrations.  In the northern breeding areas of South Australia, numbers of the butterfly tend to be more common about their food-plants during the warmer months.  Most of the migrating butterflies seen in South Australia probably have their origin from the inland areas of New South Wales and Queensland".
