The species from Amazon inhabit tropical lowland forests and equatorial forests. Bifrenaria longicornis is mostly found in flood areas along the igapós and igarapés (seasonal flood streams and small rivers of Amazon), and occasionally in open fields where the humidity is high and temperature constant through the year, normally in well illuminated places, although not under direct sunlight.Miranda, Francisco (2006). Orquídeas da Amazônia Brasileira. Ed. Expressão e Cultura, 1996. B. venezuelana inhabits forests in higher elevations, closer to the Andes.Castro Neto, Vitorino P. (2002). Bifrenaria venezuelana in Icones Orchidacearum Brasilienses. Amazon species are epiphyte and the only Bifrenaria species with elongated rhizome and ascendant growth.
