Luminoptera Aetherica, named from Latin lumen (light) and ptera (wings) with Aetherica denoting its ethereal bioluminescence, features translucent wings with glowing orange and blue phosphorescent spots along veins and margins, displaying intricate patterns on forewings within a 0–10 cm wingspan. Its slender, lightweight body (0–2 g) adapted for gliding has elongated antennae tipped with bioluminescent nodes. Emitting blue to aqua light (420–490 nm), it likely uses bioluminescence for communication and predator avoidance in tropical caves (20–30°C) with humid, sheltered conditions. Part of the Phosphorescent Morphidae cluster of 10 species, it represents a rare Lepidoptera genus with natural light production. The species is rare but stable, emphasizing conservation of its fragile cave habitat.
