Little free-tailed bats (2-9/month) were collected over 15 months in the eastern Transvaal lowveld (latitude 24 degrees 59'S). There was an extended but distinct breeding season of 8 months per year. Females appeared to be polyoestrous and able to bear 3 pregnancies per breeding season. There was a progressive decrease in the magnitude of the three birth peaks during the breeding season, with a concomitant slight loss in birth synchronization. Gestation period was approximately 60 days and one young per female was the rule, with implantation occurring only in the right uterine horn of the bicornuate uterus. It is suggested that offspring are weaned before the age of 21 days, and that female become sexually mature in the following breeding season at the age of 5-12 months.
在德兰士瓦东部低地（南纬24度59分），经过15个月的时间收集了一些无尾蝠（每月2 - 9只）。每年有一个长达8个月的延长但明显的繁殖季节。雌性似乎是多周期发情的，每个繁殖季节能够孕育3胎。在繁殖季节，三个出生高峰的规模逐渐减小，同时出生同步性略有下降。妊娠期约为60天，通常每只雌性产一仔，着床仅发生在双角子宫的右子宫角。据推测，幼崽在21日龄前断奶，雌性在接下来的繁殖季节，即5 - 12月龄时性成熟。
