Different species of bats roost in various places during the day, such as among foliage, in hollows or crevices, and in specialised roosts, notably caves (Figures 13, 14, 18).

Figure 13. Different views (a, b, c) of one of the bat houses in Letaba Campsite, Kruger National Park. These bat houses provide alternative roosts for molossid bats, which likely control insect populations, including mosquitoes (© F. P. D. Cotterill).
