I went out in the yard about 200 AM and looked at the hive. There were 3 big ole cockroaches munching down on white undeveloped bee carcasses. I don't know if the bees tossed these undevloped pupae out or the roaches went in and got them. The guard bees weren't doing much, and even let the roaches nibble on them. I was waiting for a mad rush of defender bees to overwhelm the roaches and kill them It didn't happen. Any thoughts?
