Living World - Glow Worms

This week on Living World, presenter Chris Sperring is in Buckinghamshire on the lookout for glow worms. Literature is full of references to these enigmatic little beetles who glow when its dark enough not to be able to differentiate colours. With Chris is Robin Scagell who has been studying glow worms for over 40 years and still gets a sense of excitement seeing one in some long grass by a lake near Little Marlow. While recording the programme, Chris witnessed a male come to a female and mate with her; something that is very rare to see in the wild. Producer Andrew Dawes.
