  7. Reproduction • Mating season for D. auratus occurs throughout the entire rainy season from mid-July through mid-September. • Male frogs go through an elaborate ritual to attract mates. The males vocalize, a trill sound, to attract females. Once the courtship ritual is complete the females deposit up to 40 eggs on leaves. The eggs are encased in a gelatinous substance for protection against desiccation. • During the two-week development period, the male returns to the eggs periodically to check on them. Once the tadpoles hatch, they swim onto the male’s back and he carries them to a place suitable for further development, such as wet holes in broken trees and branches, little ponds, and wet coconut-shells.
