Old, obscure question.

[Dracolich5]

   Forgive me if I don't sound very technical, but this question is based on a
show I saw years ago.  I heard of a type of butterfly larva in Australia that
enters ant hives and eats the developing grubs.  This caterpillar, if I
remember, was an orange color, and shapped like a plate with the edges curled
up.  Does anyone know what the name of this butterfly is?  Is there a good
webpage with an image of the adult phase?  Thank you for listening.
