 The range of frequencies that the moth is most sensitive to is usually associated with the frequencies used in echolocation by the sympatric bat community.In the presence of predatory bats, it has been shown that the Lepidoptera species "Mythimna unipuncta" (true armyworm) stops mating behaviors, such as female calling and male wing flapping.As well, hearing is important for mating behaviors in this species because females increase their flapping frequency around males and males produce a trembling noise in response.
