![]() ![]() "Prior to the evolution of bats we would expect to find ears in relatively few insects, but after that we should see ears in more insect groups," he explained.ĭid insect ears get an upgrade when bats came to be? Before this study the fossil evidence for insect hearing was too poorly preserved or scantily described to know for sure. "The big evolutionary trigger for the appearance of hearing in many insects is thought to be the appearance of bats," Plotnick said. Insects that evolved such supersensitive hearing would have had a crucial survival advantage, scientists say. Crickets, moths and other flying insects have ultrasound-sensitive hearing and can hear bats coming, diving or swerving in midflight to avoid being eaten. But many species can also pick up sounds beyond the range of human hearing, such as the high-pitched sonar of night-hunting bats. Think of the chorus of crickets, or the love songs of cicadas. Modern insects use their ears to tune in to each other's chirps, trills and peeps. Plotnick and co-author Dena Smith of the University of Colorado, Boulder are trying to figure out when different insects got their ears, and whether predators may have played a role. Insects have evolved ears at least 17 times in different lineages. ![]() "Insects have ears on pretty much every part of their body except on their head proper," Plotnick explained. The ears of the tachinid fly are tucked under the chin. Grasshoppers have ears on their abdomens. Insects hear with help from unusual ears, said co-author Roy Plotnick of the University of Illinois at Chicago. view moreĬredit: Specimen number 45545 from the University of Colorado Museum Photo courtesy of Dena Smith.ĭurham, NC - How did insects get their hearing?
