Plural of glowfly; small insects capable of producing light through bioluminescence, similar to fireflies or lightning bugs.
A compound of 'glow' (from Old English glōwan, meaning to shine) and 'fly' (from Old English fleoge). This is a relatively modern term used as an alternative or regional name for bioluminescent insects.
Glowflies and fireflies are actually beetles, not true flies—their bioluminescence comes from a chemical reaction inside their abdomens that doesn't produce heat, making them the most efficient light source nature has ever invented.
