What a great read. For a book last published in 2002, I couldn't find any better on the topic of glow worms, the insect. All the other literature (with the exception of John Horne's also good, but much simpler book) was specialised on different topics about glow worms biology, and aimed at entomologists. This book contains good photos, simple accessible language and plenty of content to go through. Can't wait for an updated version!
