 They do not, however, overwinter, nor are they morphologically similar to a queen or gyne.The length of lifespan for the queens may be a factor that leads to more reproductive workers in southern climes that have longer breeding seasons; in northern climes, where the queen is generally alive for production of gynes, workers are less likely to be reproductive.In southern climes, where the queen frequently does not survive to gyne production, workers are more likely to be reproductive.
