Queen Cell Timeline

Calculate mating and laying timeline from a known queen cell emergence date. Perfect for purchased cells or grafting schedules.

Cell Details

The date the virgin queen will emerge (or has emerged) from the cell.

Extra margin added to the 'check by' date.

Tip: For purchased queen cells, the seller should provide the expected emergence date. If buying capped cells, emergence is typically 8 days after capping.

Assumptions & Notes

  • Virgin queens take orientation flights before mating (days 3-7 post-emergence).
  • Mating flights occur days 5-14 post-emergence in good weather.
  • Queens mate with multiple drones over several flights.
  • Egg-laying typically begins 2-5 days after successful mating.
  • Poor weather can significantly delay mating and extend the timeline.
