Glowworm or glow-worm is the common name for various groups of insect larvae and adult larviform females that glow through bioluminescence. They include members of the families Elateridae, Lampyridae, Phengodidae, and Rhagophthalmidae among beetles; as well as members of the genera Arachnocampa, Keroplatus, and Orfelia among keroplatid fungus gnats.
The Rhagophthalmidae are a family of beetles within the superfamily Elateroidea. Members of this beetle family have bioluminescent organs on the larvae, and sometimes adults, and are closely related to the Phengodidae, though historically they have been often treated as a subfamily of Lampyridae, or as related to that family. The most recent evidence is that they are the sister group to the Phengodidae, in a clade that also contains the family Omalisidae, and somewhat distantly related to Lampyridae, whose sister taxon is Cantharidae.
