This is an extremely useful tool for keeping track of the progress of a new queen being reared and mated, especially for newer beekeepers.

It is a very common issue that a newer beekeeper underestimates how long it takes for a new queen to emerge, get mated and started laying, and often they make the costly mistake of adding a new queen in a cage despite having a virgin (or just very recently mated) queen already in the hive. This tool will really help a beekeeper prevent this mistake, and help them appropriately time their inspections and queenright assessments.

This tool is very helpful too if you are learning queen rearing / grafting for the first time.

The back side of this dial also includes helpful references for the brood cycle for workers and drones, information on varroa mites in cells, the queen dot colours for different years and a day by day fillable timeline chart for queen development.

This durable, water-resistant, and compact reference will make a great part of a newbee's inspection kit, and may prove handy even for some more experienced beekeepers keeping track of busy mating yard(s).
