Biofluorescence reveals nature in a new light

A phenomenon where living organisms radiate fluorescent colours under a special kind of light is showing the natural world in a whole new light.

Biofluorescence happens when organisms absorb light and re-emit it at different wavelengths when a high-energy ultraviolet (UV) or blue light is shone on them.

The phenomenon has been observed in plants, animals and insects and typically presents in vibrant colours.

Nature guide David Atthowe, who leads biofluorescence night walks in Cumbria, said the experience was like "being given a new set of eyes".

Atthowe runs Reveal Nature, a company offering nature experiences and therapy including forest bathing and biofluorescence walks.

He first discovered the phenomenon through a TED talk he saw on YouTube.

"I was living in Indonesia at the time," he said, adding: "I started experimenting, playing about with torches, and its been six to eight hours a night, every night, for the last three and half years now."

He said the habitat and climate of sites like Wild Haweswater were "brilliant" and "under-appreciated".

"The biofluorescense there is incredible," he said, adding: "It's a very special place."

He has shared a selection of his photographs.
