We can find a big variety of social organizations and mating systems in order Chiroptera. The most common is polygamy where paternal care is typically missing. In temperate zone, there is seasonal change of climate what is influencing sociality and mating of Chiroptera which are adopting so called temperate cycle. This cycle is characteristic also for our species Myotis. During summer, females live in nursery colonies to make the nursing of the youngsters easier. In every specie of this order living in Czech Republic females are having only one cub. Shelters of the nursery colonies are for example in the cavities of trees, buildings or other gaps. Myotis myotis and M. Blythi, which originally occupied the caves, in our conditions are living in buildings. Number of individuals in the colony varies and depends on type of shelter. In species M. bechsteinii, M. nattereri and M. daubentonii, female colonies are disrupted into several sub-groups living in different shelters. This social organization is called fission-fusion. Even though males are being solitary during this period of time, we can find them also in female groups or they can form an only male group. Mating occurs usually in autumn when nursery colonies break up, probably during swarming. In winter, they are hibernating in their hibernacula which are...
