Research Press Release Communications Biology July 9, 2021 The discovery of a fossilized insect wing, the features of which provide the earliest evidence so far of wing-based communication in insects, is reported this week in Communications Biology. The finding suggests that insects may have been using their wings to broadcast information since the Late Carboniferous period (approximately 310 million years ago). Many insects use wing shape, colour or sound, to attract mates or deter predators. How and when these behaviours evolved has been uncertain because structures used for communication are difficult to distinguish from those used for other purposes in fossilized wings. André Nel and colleagues discovered a fossilized insect wing in Liévin, France, belonging to a previously unidentified species of giant predatory grasshopper-like insect Titanoptera the largest of which had wingspans in excess of 33 centimeters. The authors have named the new species Theiatitan azari
