Insect Uses Its Leaf-Like Camouflage to Attract Potential Mates
Researchers found the leafy wing sections also amplify calls, and females preferred the lower-pitch songs in tests.
- Male katydids use their leaf-like wing structures to amplify mating calls, helping them attract mates while providing camouflage, researchers from the University of St Andrews found.
- Previously, scientists believed physical adaptations for survival and reproduction functioned in conflict, but this study reveals how the Viadana brunneri evolved structures serving both defensive and reproductive purposes simultaneously.
- Bioacoustic experiments revealed that leafy wing portions vibrate to amplify songs, while females preferred lower pitch calls from males with intact wing structures.
- Published in the Proceedings of the Royal Society, the study provides a rare example of natural and sexual selection acting in harmony, where traits simultaneously improve survival and mating success.
- Conducted on Barro Colorado Island in Panama, this research offers insights into how complex evolutionary traits function in tropical species as scientists explore katydid behavior.

Leafy camouflage reshapes katydid love songs, making males more attractive to females
New research from the University of St Andrews has discovered that insects who conceal themselves as leaves also use their leafy camouflage to amplify mating calls, making themselves more attractive to the opposite sex. The research published in Proceedings of the Royal Society B is the first demonstration of how impressive leaf mimicry can also be used to enhance the attractiveness of a sexual signal.
Big wings and sweet songs: The mating lives of Panama's katydids
When it comes to reproduction, animals will pull out all the stops to attract a mate. Sending out noisy mating calls, showing off colorful wings, inflating a throat pouch, and shaking a literal tailfeather all ensure that the next generation of a species happens. Some insects will go as far as making themselves look like an entirely different living thing—leaves. Usually used as a means of camouflage, male katydids appear to use their leafy dis…
