As I reported yesterday, I spent time trying to verify that each of my mating nucs did in fact have a queen that had emerged from her queen cell that I had installed on April 1st. I was successful in finding all 13 of them. Their challenge now is to survive their mating flights.
To give you an idea of the difficulty in finding a young queen among all the other bees – try to find as many of the queens as you can. There is only one queen in each picture.
