i wanted to bump this thread up in the line......swarm season is upon many of us! also, many of us will be ordering package bees and nucs, and also dividing and requeening hives. swarm cells will develop, as will supersedure cells and emergency cells. swarm cells will be being built and present in the spring for any colony over 1 year old. with package bees, there is always a high probability that one will experience a supersedure, and sometimes with requeening. this guide is just another tool to help you determine the differences of the different types of queen cells. when you see cells present in the hive and are still unsure, snap a pic, post it, or describe it, most of us can tell you what it is or isn't. (go to the first post for the pdf file and link to this guide).
enjoy your spring! enjoy your bees!
