Habitat and Ecology
It is a terrestrial species, inhabiting páramo grassland, and is not found in degraded areas. Breeding takes place by direct development.
It was previously common, although its current population status is not known.
Habitat loss, as a result of agricultural expansion (potato farming and livestock ranching), represents the major threat to the species.
It is not known to occur in any protected areas, so protection and maintenance of existing habitat is a priority. Further research is needed into the biology and population status of this species.
