Rusty bats are seasonally monoestrous and give birth to twins during November. Spermatozoa are present in the epididymides from March to August but absent from the testes from April until September. Males thus store spermatozoa in the epididymis for 5 months of the year (April-August). Mating is initiated during April with uterine horns exhibiting a 3-fold increase in sperm volume between April and July samples. It is concluded that ovulation and fertilization occur during the second half of August. Up to 5 conceptuses per female were recorded, but a maximum of only 2 implantations was observed.
锈迹蝠是季节性单次发情的，在11月产双胞胎。附睾中从3月到8月存在精子，但睾丸从4月到9月没有精子。因此，雄性一年中有5个月（4月至8月）将精子储存在附睾中。交配在4月开始，从4月到7月的样本中，子宫角中的精子量增加了3倍。得出的结论是，排卵和受精发生在8月下半月。记录到每只雌性最多有5个胚胎，但最多只观察到2次着床。
