Common glow-worms are actually bioluminescent beetles. It is the females which glow most noticeably - the larvae and adult males produce only a faint glow. The larvae are predatory and hunt slugs and snails, but as adults they rarely feed. Females have only a few weeks in which to attract a mate and lay eggs. After this, they die. As well as attracting a mate, the glowing abdomen is a warning to predators to stay away - glow-worms taste bad and contain chemicals that cause vomiting.
Scientific name: Lampyris noctiluca
