When you bought your bees last year, did you notice the queen had a color on her? Unless you have purchased bees more than once, you might not know that the color on the queen bee changes each year. This helps identify the age of the queens we get from different distributors.
Here is how the colors are determined.
Years ending in:
1 or 6 are White Dots
2 or 7 are Yellow
3 or 8 are Red
4 or 9 are Green
5 or 0 are Blue
Now, the next time you get a marked queen, you will know how old she is :)
