Male Ailao moustached frogs develop nuptial spines on their faces during the breeding season. Adult frogs are often found close to forest streams where they breed. The male frogs construct and guard nests under rocks in streams aggressively defending nesting sites and eggs against other males by jostling them with their spines. Male frogs call from underwater to attract the females. The streams they breed in are cool and tadpoles may take several years to metamorphose and during this time may reach a total length of nearly 12 cm. On Mount Fansipan this species has been reported from elevations between 1,900 and 2,500 m asl.
