This species is known only from the lowlands up to 900m asl in the States of Rio de Janeiro and São Paulo, in southern Brazil. Records from Rio Grande do Sul in extreme southern Brazil probably refer to other species.
Habitat and Ecology
It lives in terrestrial and epiphytic bromeliads inside primary, secondary and seasonally flooded forests where it lays its eggs. The larvae develop in bromeliads. It does not survive in heavily degraded areas.
It is a common species.
The major threats are habitat loss due to livestock grazing, clear-cutting, collection of bromeliads, and human settlement.
It occurs in several protected areas.
