Natural History
This species is very common and very generalized. It is found in dry forest and wet forest habitats. It is common in Winkler samples and at baits. Nests are found in small cavities (under dead wood on ground, in dead sticks, in dead knots on tree trunks, under bark flaps, under epiphytes) from litter layer to high canopy.
