Are there echolocating insects? Echolocation is the ability to obtain spatial information of the surroundings from echos generated by the animal. There are bats and other vertebrates that naturally use it. I was wondering if this is limited to vertebrates, or if there are examples among the invertebrate, especially insects.

Some moth actually do use clicks for their own echolocation: "Noctuid moths (Noctuidae) are the only group of invertebrates for whom echolocation was demonstrated":
