Natural Swarm Calendar

Handy chart showing the relationship between the development time for new queens, swarming and hive population.

The important thing to remember about queen development is it can take about a month from an egg in a queen cell till that egg turns into a mated laying adult queen. I have personally seen new queens laying in the range of 25-32 days from queen egg being laid. Others say 28 days plus or minus five days.

During that time:

  • Population will decrease due to the swarming bees leaving
  • Then population will increase for three weeks as existing brood emerges
  • Then population will decrease for three weeks as brood from the new queen develops into adults.See the pdf version of the chart below.
