ABSTRACT
The relationship between light and insects, like all other living organisms, is complex. Light is essential to life, but can also be dangerous, even deadly. To manage these electromagnetic interactions between the outer world and the body of arthropods in particular, nature has developed structures at the interfaces (wings and cuticle) adapted to different constraints.We deal first with incoming light, i.e. the “solar absorber” insect: how it optimizes the absorption, how it prevents overheating, etc. In a second part, we discuss outgoing light, or the “LED” insect. Many insects emit light by fluorescence or bioluminescence, and have much to teach us about its extraction. Bio-inspired avenues of research and achievements are presented.
