Some facts about the glow worm

   The glow worm or glowworm is a luminous nocturnal beetle, in which the female is wingless, the male winged, and provided with large eyes. The luminous organ, situated at the end of the abdomen beneath, is present in both sexes, but more powerful in the female, which may frequently be seen on summer nights amongst the grass. The adult insects seldom feed, but the larvae devour snails and slugs.
