Rhagophthalmidae, a family of beetles that live in Asia, have organs that glow. These beetles might be relatives of the firefly but it is not presently confirmed. Very little is actually known about these beetles. The females are wingless and look like larvae when at their final stage of development in the lifecycle.
Not to be confused with glow worm beetles, the glow worm has the amazing ability to produce light naturally and they can only be found in Austrailia and New Zealand. The process that the glow worm uses to produce light is called bioluminescence. During this biochemical reaction several components work together to emit light.
The glow worm may attract the most attention when it comes to intrigue and beauty, but there is another worm that may attract attention for an altogether different reason. This worm is so odd looking, that one can’t help but wonder “what kind of worm is that?” The black and yellow worm dangling from a lone leaf or making its way up the trunk of a tree is commonly called a Catalpa Sphinx. Cool name for a cool worm, huh?
If you think you can make an average, everyday worm glow in the dark by feeding it certain foods or poking it with a stick, think again! Not to be confused with glow worm beetles, glow worms have the amazing ability to produce light naturally and they can only be found in Australia and New Zealand.
Nightcrawlers, a popular brown fish bait, are now sold as glow worms. The glow-in-the-dark green nightcrawler worms are quite attractive to catfish and other game species.
