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 Their high intensity calls are necessary to even have moderate detection of surroundings because air has a high absorption of ultrasound and because insects’ size only provide a small target for sound reflection. Additionally, the so-called "whispering bats" have adapted low-amplitude echolocation so that their prey, moths, which are able to hear echolocation calls, are less able to detect and avoid an oncoming bat. Calls can be composed of one frequency or multiple frequencies comprising a harmonic series. In the latter case, the call is usually dominated by a certain harmonic ("dominant" frequencies are those present at higher intensities than
