Common throughout the Reserva Florestal Adolpho Ducke in Brazil.

Life History, Abundance, Activity, and Special Behaviors
The species is arboreal and nocturnal, and is found in primary and secondary forests, usually on trunks and branches. Males call, often in groups, from low vegetation or immersed in small water bodies. Reproduction occurs throughout the year, after heavy rain, but most frequently at the start of the rainy season. The clutches contain about 2000 black eggs that are deposited as a film on the surface of temporary ponds. The tadpoles are voracious predators of eggs of their own and other species,

Comments
Male Osteocephalus oophagus differ by having a single vocal sac, and smaller size. Some individuals of O. oophagus also have numerous white spots on the sides of the body.
