The emission of light originates from the presence of fluorophores in the living organism teguments. The confinement of fluorescent probes within photonic structures enables the so-called controlled fluorescence, which is known to lead to modifications of the fluorescence properties such as intensity (enhancement/inhibition) or spatial distribution (directivity of emission). Such a photonic confinement is found in several living organisms1-3. Liquid-induced fluorescence changes in insects, on the other hand, still remain under-explored. We investigate here the case of fluorescent beetles of which the macroporous photonic structures covering the elytra contain embedded fluorophores4. These structures control both the insect colouration and fluorescence. Contact with liquids turns out to induce variations of the spectral and spatial distributions of the fluorescence. [1] P.
