Have a close up look atthis photo I found on flickr.. amazing! A whole tunnel lit up with glow worms in Australia. I never realised that glow worms existed in the UK, but I was very pleased to find out that they have been sighted and photographed all over the British Isles, even as close as Southwater.. how exciting! I think I will have to go on a glow worm walk! The only glow worm I have ever seen is my one of these!
