As reported by [motherboard]:
Moths are generally nocturnal creatures. Unfortunately so are Bats, which bounce sound off their prey to locate and hunt them. As it turns out however, certain species of moth, like the deaf Madagascan Bullseye moth, have adapted by developing fur on their thoraxes, a chest-like space between the neck and abdomen. This has the effect of absorbing and muffling the sound that predators try to find them with by up to 85%. For comparison, Bufferflies can only absorb a maximum of 20%.
There are other way's that moth's have adapted in this acoustic war however, such as the [Greater Wax Moth]. This species has evolved hearing so sensitive that its smashed all known ultrasound hearing records, being able to sense higher pitches more than any other known species. Its so sensitive that they can easily hear the calls bats may try to use to locate them, allowing them to always staying one step ahead.
