Photo A Day - February Challenge - Day 27

Another hot day here today and so I have stayed pretty much inside and out of the heat, so I was stuck for a photo opportunity and decided to raid my archives again.

Any idea what has happened here?

I found the new leaves of a Eucalyptus in the forest down near Pemberton. It was not much bigger than a seedling, although through natural regeneration rather than planting, and all its leaves carefully serrated by possibly a Leaf Cutter Bee. Although my research shows that they normally eat soft leaves and that they cut in neat circles, I can't for the life of me think what else it could have been.
