Plumose Glowworm Beetle
Phengodes plumosaAlso known as Railroad Worm, Plumose Glowworm
Females remain wingless and caterpillar-like throughout adulthood, glowing continuously with bright green luminescence along their body segments to attract mates. Males feature large, feathery antennae engineered to detect subtle female pheromones floating through dark woodland understories. Predatory larvae and females stalk millipedes across damp leaf litter in North American forests.
