L splendidula

Glowworm Glow"worm`, n. (Zo["o]l.) A coleopterous insect of the genus {Lampyris}; esp., the wingless females and larv[ae] of the two European species ({L. noctiluca}, and {L. splendidula}), which emit light from some of the abdominal segments. [1913 Webster]

Like a glowworm in the night, The which hath fire in darkness, none in light. --Shak. [1913 Webster]

Note: The male is winged, and is supposed to be attracted by the light of the female. In America, the luminous larv[ae] of several species of fireflies and fire beetles are called glowworms. Both sexes of these are winged when mature. See {Firefly}. [1913 Webster]
