Attractiveness of an Ephemeroptera insect order towards artificial lights as function of CCT
Attractivité de l'ordre d'insectes Ephemeroptera envers les lumières artificielles en fonction du CCT
Résumé
This study investigates how Atalophlebia mayflies perceive artificial light at night (ALAN) depending on light color temperature (CCT). By combining known visual sensitivity curves with the spectral output of various LED lights, moonlight, and daylight, the researchers modeled insect perception. Findings suggest mayfly visual perception increases with CCT up to a point, then plateaus or decreases. Lateral eyes are more sensitive to low CCTs than dorsal eyes, possibly reflecting sex-based behavioral differences. While perception may relate to attractiveness, this needs experimental validation. Brightness and other light parameters should also be considered.
