June
Because of the summer, the fresh queen changes so you’re able to in-colony work, such putting eggs. While you are the woman is taking good care of their own brood, she actually is along with generating pheromones one to inhibit breeding of the workers. This is certainly known as “pre-competition stage” in which the queen is the sole egg-covering to the nest.
