Life History, Abundance, Activity, and Special Behaviors
The species is terrestrial, active by day and night, and usually found in open areas and edges of forests. Reproduction occurs throughout the year, with a peak in the rainy season (December to May). The males call from the ground, hidden among leaves and fallen branches. Males excavate small burrows in the soil, in which the female deposits about 15 eggs in a foam nest. The tadpoles develop in the nest, living exclusively on the yolk provided in the eggs.
Similar species: Adenomera andreae differs by the distance from the eye to the tip of the snout being only about the diameter of the eye, its glandular dorsolateral folds being fine and difficult to see with the naked eye; its pectoral region and undersides of arms being darker than the belly. The posterior region of the belly and thighs are grayish in A. andreae.
