Not much detailed information is available regarding mating system of this species. Maternity roosts often contain 50 to 400 females with males often present.
Information on reproduction is sparse. Breeding is thought to occur once per year. Females give birth to one offspring which weighs approximately 4 grams at birth, and is ready to fly in early to mid August. In Bulgaria, young are ready to fly in mid July.
Within the genus Rhinolophus, some species are known to undergo delayed fertilization. Mating may occur in winter, and gestation, which is usually about 7 weeks, occurs in early spring. Most births in this genus occur in late spring or early Summer. Given that the young are flying in July or August, it is likely that Rhinolophus eurylate is similar.
In species of Rhinolophus for which data are available, lactation lasts for approximately one month. Sexual maturity is usually reached by two years of age.
Breeding interval: The animals breed once annually.
Breeding season: The breeding season of this species has not been reported, but is likely to occur in winter or in early spring.
Range number of offspring: 1 (high) .
Average number of offspring: 1.
Average gestation period: 7 weeks.
Average weaning age: 1 months.
Average age at sexual or reproductive maturity (female): 2 years.
Average age at sexual or reproductive maturity (male): 2 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
No information about parental care is available, but in general females care for young in bats. Young bats are typically atricial, and in this genus, lactation is thought to last for about one month. The role of males in parental care has not been reported.
Parental Investment: no parental involvement; altricial ; pre-fertilization (Protecting: Female); pre-hatching/birth (Provisioning: Female, Protecting: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Protecting: Female)
