Reproduction

Calling males have been observed during the daytime; one called from a stone at the edge of a river. The call consists of 20-29 notes, lasting 1–2 seconds. Females lay the eggs on land. Tadpoles are transported to streams by adults and develop in quiet pools in or adjacent to the watercourse. A newly metamorphosed juvenile frog measures about 12 mm.
