Lucidoptera Phosphorradiantus, named for its bright and radiant phosphorescence, is a bioluminescent butterfly within the Aurorae Lepidoptera cluster of ~20 species. It features translucent wings up to 10 cm with visible venation and subtle orange bioluminescent patches emitting blue-green light (450-495 nm). The slender body and long antennal segments support agile hovering flight in temperate forest understories (20-30°C). Weighing under 2 g, its bioluminescence is localized at wing veins and margins, likely aiding communication or predator deterrence. Vulnerable to habitat disruption, this species is a specialized lepidopteran adapted to low-light environments, highlighting its ecological niche and conservation importance.
