''Lampyris noctiluca'', the common glow-worm of Europe (see also "glowworm"), is a firefly species of the genus ''Lampyris''. These are beetles, as evidenced by the hard cases which close over the wings when they are not in use. ''Lampyris noctiluca'' presents a conspicuous sexual dimorphism. The males are winged, with brown elytra, a clearer pronotum and a large brown spot in the middle, while females are larviforme, wings are missing and they are often twice the size of the males (up to in length). These beetles use their bioluminescence to attract mates. The adult females are mostly famed for their glow, although all stages of their life cycle are capable of glowing. In Britain, this species is fairly common compared to its cousin ''Phosphaenus hemipterus'' – the lesser glow worm – which is very rare. ==Distribution== The range of this beetle stretches from Portugal and Britain in the west, right across Europe and Asia to China in the east. It also survives further north than any other firefly, almost reaching the Arctic Circle. It is not found in North or South America. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lampyris noctiluca」の詳細全文を読む スポンサード リンク
