Butterflies and plants evolved in sync, but moth 'ears' predated bats

23.10.2019

A new study examines these classic hypotheses by shining a light on the early history of Lepidoptera, the order that includes moths and butterflies. Using the largest-ever data set assembled for the group, an international team of researchers created an evolutionary family tree for Lepidoptera and used fossils to estimate when moths and butterflies evolved key traits. Their findings show that flowering plants did drive much of these insects' diversity. In a surprise twist, however, multiple moth lineages evolved "ears" millions of years before the existence of bats, previously credited with triggering moths' development of hearing organs.
