Sorry, but no pic.
It looked like a large ( (4 to 5 cm long, body bit at least half a
centimetre thick)
fat butterfly, except mostly pink with yellowish bits.
Its wings were a bit strange in so far as they were like flaps of
velvet, turned and twisted as if folded over according to whatever
position movement left them in.

It's possible my description is insufficient, but I only got to see
this creature for a few minutes. I've never seen anything like it and
I'm just curious.
It was next to a pond and at first I thought it was just a fallen leaf
with something like peach-curl.
