It used to be a commonly believed legend that Queens only go on one maiden flight, however it is now supposized that more than one maiden flight can take place but these will be close together. After that provided she has not been clipped she will only fly when she swarms, this of course could happen more than once in a season or her life.
Poly Hive, some (and these are old timers) were indicating that beyond the initial group of mating flights, and maybe a year or two later she can venture out, sometimes taking a few hundred bees with her (not a full swarm) mate again and then return to the hive. A sort of false swarm.
Personally I don't believe a word of it, and it would appear that no one has documented such an occurrence. I'd love to be proved wrong though!
