 The males mate with the new reproductive females (from both their own and separate nests), although they do not attempt mating with the non-reproductive females.Impregnated females may continue to live in their mothers' nests, although it is thought that they only forage for their own food and do not contribute to the rest of the nest.With the arrival of the colder autumn weather, the males and non-reproductive females die off, and the impregnated reproductive females go on to spend the winter in diapause and repeat the lifecycle the following year.
