Saccopteryx leptura

Saccopteryx leptura

Adults have a body length of 4 cm, forearm of 4 cm and weight of 5 g. The dorsal color is brown with normally visible longitudinal stripes. They have, near the forearm, odoriferous glandular bags.
 
They live in small colonies of up to ten individuals, sheltered in more open places like shallow crevices in tree trunks. In the reproductive period they tend to form monogamous pairs.
 
They occur in riparian forests. They defend a foraging territory, where they hunt flying hymenoptera. They usually forage in more open areas within the forest. The call is made up of two pulses of almost constant frequency, the first with an average frequency of 48 kHz and the second of 55 kHz.
 
Its distribution includes Colombia, Venezuela, Trinidad and Tobago, Guianas, Brazil, Ecuador, eastern Peru and northeastern Bolivia.
