During the day, the nocturnal Schlieffen’s bat tends to roost in groups in tree hollows (3) (8), rock crevices (9), and in various buildings (6). It emerges from roosting just before dusk, hence its alternative name of ‘twilight bat’, to begin foraging (2). As an insectivorous species, Schlieffen’s bat depends on marshes, streams, riverside forest and floodplains for foraging, where an abundance of insects may be found (10) (11); however, floral matter has also been found in its faeces in some areas, suggesting a degree of omnivory (12). In contrast to its social roosting behaviour, Schlieffen’s bat tends to forage on its own (13).
Schlieffen’s bat reproduces once a year, with mating occurring in June (4). However, the eggs are not fertilised until late August, when ovulation occurs; in the intervening period, the male sperm is stored in the female’s uterine horns (14). The majority of offspring are born in November (4), with each litter containing one to four offspring (14).
