After a few years of buying Italian queens and a few pounds of stock Italian bees I was under the impression that queens just laid eggs for one subspecies i.e. Italtion, Russian, Carnolian and such. To my surprise, after capturing enough feral bees from a structural removal for two hives, these bees are quite different. There are small dark ones, medium size yellowish ones, and some bees that look greyish and a bit larger. The drones seem quite similar and greyish. Is this my imagination or do queens that mate freely produce a variety of female offspring from different drones?
