I have been looking at my records, and I took notice that one of my hives has superceded its queen every mid-August since 2009. I thought it must have been coincidence, because they did not do it this year. However I looked into that hive today, and the original queen has been superceded!? There is a fresh new unmarked queen in the hive, and this is also the only hive that has not yet evicted the drones. It also has had the lowest mite loads every year. So I am wondering if anyone else has experienced something like this too. Also, what do you think, it is just happenstance, or a desireable trait? Thanks in advance!
