According to the researchers Glow worm refers to various groups of insect larvae and adult larviform females that glow through bioluminescence. These species may sometimes look like worms, but actually they are from the category of insects. There are some special features of these worms that they can glow as long as a match stick and they sometimes resemble a maggot. The secret of their glow is under their tail that glows because of chemical reactions, called bioluminescence.
