Occurs throughout the Reserva Florestal Adolpho Ducke in Brazil, and is frequently found near large ponds.
Life History, Abundance, Activity, and Special Behaviors
The species is arboreal and nocturnal. Males usually call from high trees, and descend with the female to construct nests 1- 3 m above ponds. Reproduction occurs throughout the year in ponds near to, or far from, streams, with a peak from November to May (rainy season). The females deposit about 600 unpigmented eggs in a gelatinous mass in leaf nests hanging over ponds. The leaves are joined or folded with the aid of the male. After 8-10 days, the tadpoles hatch and fall into the water, where they complete development until metamorphosis.
Similar species: Phyllomedusa tarsius differs by having a red-orange iris with black reticulations, and by having brown first and second fingers with white tips. Phyllomedusa vaillanti differs by having purple coloration on the sides and belly, adhesive discs on the fingers that are orange or dark purple, and a silvery-gray iris.
