How many of these failures to supersede are the result of the new queen getting lost on her mating flight and no more resources to make a new queen? In my experience the old queen is not eliminated until the new queen is back and mated and ready to lay eggs or already laying eggs. I have found marked superseded queens dead on the landing board twice. In both cases the queens abdomen was shrunk up so small she looked like a worker but as she was color marked I knew it was the old queen. In both cases the hive had a laying queen the day I found the old queen dead. Did the bees simply stop feeding the old queen once they had a new queen and she starved in a day or two?
