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
Lesser long-eared bat sight is mostly restricted to aerial prey while they a technique that the species uses to take advantage of seasonal booms of tettigoniid crickets as well as general ground and aerial prey, known as passive listing. This method of hunting does not rely on sight or echolocation. Some moths species, like noctuids, have evolved to develop their own form of "ears" that are able to pick up the frequency of bat calls, however they are unable to sense long-eared bats as the bats use a minute whispering technique different from echolocation which bounces off the moths and is picked up
