Our queens mate with great success starting at about 60 degrees F. Some varieties of bees may fly better at cooler temperatures.What about everyone worried about the temp being close to 70 degrees for mating flights. We have lots of swarms april and may and temps don't start climbing till june. Say i start grafting April 15 - 25 and the would put mating around second or third week of May. Would this work? I have one colony thats bursting at the seems with bees right now and would make a great hive to graft from and raise queens for my splits.
