Some notes and observations of Glow Worm larvae in captivity
 
 
Larva 11 remains as the only larva from the 11 captive larvae used during our 2012 research. This presents us with the ideal opportunity to observe and then compare larval bioluminescence produced by the same larva over two years. Scroll down for the 2013 results.
