Morales G 1986 studied “the effects of cavity size on demography of unmanaged colonies of honeybees” & found that supersedure occurred in 50% of colonies in hives with 84 L of space but only 5% of colonies in hives with 21L and with 42L space (these tended to replace their queens by swarming)
84 litre hive is only size of 2 langstroth boxes. A colony must swarm every year in that cavity. Unmanaged colonies are escaped swarms. Varroa has killed fetal bees after 1986.
When I bought mongrel black bee swarms in Finland 50 years ago, very often the swarm superceded the old (laying) queen 1 month after swarming.
Perhaps the queen was from primary swarm of privious year. Impossible to know.
i renew my queens every year. I have very seldom superceding colonies.
