Life History, Abundance, Activity, and Special Behaviors
The species is arboreal, nocturnal, and frequently found in wetland near streams in forest. Reproduction occurs throughout the year, with a peak in the rainy season from November to May. Males frequently call from hidden positions under leaves. The females deposit about 400 eggs in ponds that are normally near streams. The tadpoles are dispersed and hide in the leaf litter in ponds.

Cochranella oyampiensis differs in having a transparent belly, greenish iris, and T shaped discs on the tips of fingers.
