    Found this interesting about capping times for emergency queen cells, which is often of concern when making splits.

    "The average interval from egg laying to queen cell capping was 8.8 days and ranged from 7 to 12 days. The average interval from queen cell capping to queen emergence was 7.2 days and ranged from 5 to 8 days. The whole development time from egg laying to queen emergence was 15.7 days, ranging from 14 to 18 days. The age of brood at the moment of dequeening positively correlated with both the time of capping and the total queen development time. The average age of brood (at time of dequeening) around which queen cells were built was 3.0 days. However, higher proportions of queen cells with younger larvae were destroyed; in effect, the age of brood at dequeening from which queens emerged was 3.4 days. "

    The experiment used only 4 colonies.

    Sounds about right to me. I've had queens emerge as early as day 14 when the weather is really hot and as late as day 18 when the weather is really cool.

    7 to 12 for capping sounds like a bit more range than I would have figured. I would figure more like 7 to 9 maybe.
