The Biggest Moth Ever Recorded Stuns Scientists—Here’s Why It’s Obsessed with Light! When researchers recently documented the largest moth ever recorded, they didn’t just marvel at its size—they were completely baffled by its uncanny obsession with light. The discovery has fascinated entomologists and sparked new questions about how nocturnal insects interact with artificial and natural illumination. Here’s a deep dive into this extraordinary creature and why its strange attraction to light is capturing scientific attention worldwide. ### The Giant Moth: How Big Was It? The title of “biggest moth ever recorded” belongs to a colossal specimen of the Atlas moth (Saturnia promethea), though some recent sightings suggest even rarer species with wingspans exceeding 24 cm (almost 10 inches). Such wing measurements dwarf most known moth species—many of which top out around 15–18 cm. Scientists believe this moth’s extraordinary size may result from genetic anomalies, optimal environmental conditions, or a rare convergence of survival advantages.
