The greater mouse-tailed bat lives in large colonies, sometimes containing over a thousand individuals (2). Its diet varies depending on the time of year and the location; for example, a population of bats in Iran was found to feed almost exclusively on beetles (4), while in Israel, during the summer months, the greater mouse-tailed bat is known to feast on carpenter ants during their massive nuptial flights, in which male and female ants emerge from nests to mate (5).
Over autumn, the greater mouse-tailed bat accumulates fat and almost doubles in weight, allowing it to survive for several weeks without any food or water during the harsh winter months when insect prey is scarce. As a result, the greater mouse-tailed bat does not need to hibernate and instead remains active throughout the year (1) (2).
Female greater mouse-tailed bats mate in spring, around March, giving birth to a single young in June or July after a gestation period of around 18 weeks. The young are weaned after six to eight weeks and become sexually mature in their second year of life (2).
