The will-o'-the-wisp phenomena may occur due to the bioluminescence of various forest dwelling micro-organisms and insects. The eerie glow emitted from certain fungal species, such as the honey fungus, during chemical reactions to form white rot could be mistaken for the mysterious will-o'-the-wisp or foxfire lights. There are many other bioluminescent organisms that could create the illusions of fairy lights, such as fireflies. Light reflecting off larger forest dwelling creatures could explain the phenomenon of will-o'-the-wisp moving and reacting to other lights. The white plumage of Barn owls may reflect enough light from the moon to appear as a will-o'-the-wisp; hence the possibility of the lights moving, reacting to other lights, etc.
