[4] Like many other bats, this species is insectivorous; they eat a variety of insects including Lepidoptera, Hymenoptera, Homoptera, Coleoptera, Hemiptera, Orthoptera, Diptera, and Neuroptera.

In June and July, Lepidoptera accounted for the greatest volume of prey while diets in September and March consisting mostly of Hemiptera[5] Table 1.

The roosts are located in caves, crevices, mines, tunnels, and man-made structures [6] with colony sizes less than 100 individuals.

The gestation period is about 70 to 90 days and when the young are finally born, they weigh 3-4 grams, or about 22% of the adult weight.
