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
Barbastelle this world, participated in an evolutionary arms race. The foe for the bat order Chiroptera is its prey, the moth order Lepidoptera. To minimize the risk of the bats' echolocation, moths [and in rarest examples, butterflies] have evolved to detect the echolocation calls of hunting bats, and evoke evasive flight manoeuvres, or reply with their own ultrasonic clicks to confuse the bat's echolocation. The Arctiidae subfamily of Noctuid moths uniquely respond to bat echolocation in three prevailing hypotheses: startle, sonar jamming, and acoustic aposematic defence. All these differences depend on specific environmental settings and the type of echolocation call; however,
