This species occurs in Andean Valleys from southern Colombia to Central Ecuador. Its altitudinal range is from 2,200-3,400m asl.
Habitat and Ecology
Normally this species is found in grasslands and cultivated areas in inter-Andean Valleys (Lynch, 1981). The species occurs in the forested regions in the humid temperate and humid sub temperate regimes (Lynch and Duellman, 1997). It has also been reported to occur in pastures, ditches, shrubs, crops, forest edges and urban areas (Mueses-Cisneros, 2005). By day individuals have been found beneath rocks, dirt clods, wood, bricks, paper, or under the cover of grass (Lynch and Duellman, 1980). At night, males are actively calling on low herbaceous vegetation within one meter of the ground. Reproduction appears to be year-round (Mueses-Cisneros, 2005). It breeds by direct development and lays its eggs in burrows excavated by the frogs themselves. It can be found in heavily disturbed habitats including downtown Quito.
An abundant species in Ecuador, this frog is heard whenever it rains in Quito.
It is threatened only by heavy agrochemical pollution.
In Ecuador, its geographic range overlaps with Reserva Ecológica El Angel, Reserva Ecológica Cotacachi-Cayapas, Reserva Ecológica Cayambe-Coca, Reserva Geobotánica Pululahua, Parque Nacional Cotopaxi, Reserva Ecológica Los Illinizas, and Reserva de Producción Faunística Chimborazo.
