The glow is living behavior, not mineral phosphorescence. Larvae use blue-green light to attract tiny prey in humid rock shelters; darkness, moisture, season, and careful light discipline determine whether visitors see it.
Night tours sell out and flashlights or phone screens can ruin dark adaptation for everyone. Day trails include wet rock, stairs, roots, and confined passages; this is not a casual paved glow display.
