| Bats in the genus Rhogeessa are very tiny and are known for their low, slow, fluttering flight. Often 2 to 5 of them are seen flying together, hunting insects. If they are over a clearing, they tend to fly in a circular pattern, and if they are over a forest trail, they go back and forth, covering about 30 m of trail before turning and heading in the other direction. Allen's Yellow Bat is found in only in Mexico, from Oaxaca to Zacatecas.
Total Length: 81-90 mm
