That actually sound like a leaf cutter bee. They are native bees and unlike the honey bee are solitary. A single female collects leaf segments and takes them to line a nest for her larvae.I used to also get semi-circular chew marks on the margins of the fresh open leaves. Initially thinking it was caterpillar, but later found out was wasps chewing the leaves and rolling the pieces into small cones - then flying off with them, to do whatever wasps do?
