Psychrophrynella wettsteini occurs in upper cloud forest and humid páramo grassland at elevations of 2,900–3,900 m (9,500–12,800 ft) above sea level. Individuals have been found under stones. They can be active by day and night, including calling activity by males.[1][3] The diet consists of insects.[3]
