Habitat. Primary humid forests. The only specimen of Orces’s Long-tongued Bat was found on a small, flat, densely forested river terrace. Collection site is part of the Subtropical Zoogeographic Region in Very Humid Pre-montane Forest. This forest has at least two relatively undifferentiated strata. Canopy of upper stratum is open and discontinuous; lower stratum is denser and nearly continuous. Trees have relatively slender trunks and heights of 15-25 m. Young palms and saplings of other tree species are plentiful in understory, which includes tree ferns and mosses. Epiphytes including large leaved Arecaceae , orchids, and bromeliads are conspicuous. Mean annual temperature is ¢.20°C, humidity is high, and annual precipitation can exceed 4000 mm.
