Illuminoptera Spectra, named from Latin 'illuminare' (to light up) and 'ptera' (wings), is a bioluminescent butterfly with translucent wings displaying amber and ochre patterns highlighted by blue-green luminescent spots (420-490 nm). It has a wingspan of 0-10 cm, a slender body weighing up to 5 g, and elongated filamentous antennae aiding navigation during rhythmic gliding flight in tropical rainforest canopies. Part of the 'Lumina Nocturna' cluster with 10 congeneric species, it thrives at 20-30°C. Its bioluminescence functions as mating signals and camouflage from nocturnal predators. Near Threatened due to habitat specificity and environmental threats, Illuminoptera Spectra is vital for ecological and evolutionary research.
