Leaf-nosed bat rounded tips, range in body size from 4 cm to 13.5 cm and a wingspans of up to 90 cm or more. Like other bats, leaf-nosed bats are nocturnal foragers that use echolocation to locate food sources, though the food sources they are locating vary between species. Many bats in family Phyllostomidae appear to have limited reliance on echolocation, likely because frugivorous bats do not need to quickly identify flying insects like many other bats. Instead, species of leaf-nosed fruit bats appear to use scent to identify their preferred food sources. When they are not foraging, leaf-nosed bats roost in
Animal echolocation as 212 kHz. Insectivorous aerial-hawking bats have a call frequency between 20 kHz and 60 kHz because it is the frequency that gives the best range and image acuity and makes them less conspicuous to insects. However, low frequencies are adaptive for some species with different prey and environments. "Euderma maculatum", a species that feeds on moths, uses a particularly low frequency of 12.7 kHz that cannot be heard by moths. Echolocation calls can be composed of two different types of frequency structure: frequency modulated (FM) sweeps, and constant frequency (CF) tones. A particular call can consist of one, the
