What's he doing?

This little bee was struggling to fly carrying a piece of leaf. He had to keep landing to rest and his flying was all over the place. what's he up to and why? Anyone know?

Making nest. It makes a tunnel, takes bits of leaf down it and lays an egg in each one.
           I watched one last year do this in a flowerpot and followed it to see where it was getting leaf from. It cuts pieces off with its mouth amazingly quickly.

It's a leafcutter bee at work. It takes about 6 seconds for a bee to land on a leaf, cut a piece, roll it up and fly away to the nest. Yours looks like amateur that failed to roll it up properly.
