Wikipedia
Lampyris is a genus of beetle in the firefly family (Lampyridae). In most of western Eurasia, they are the predominant fireflies. They produce a continuous glow; the larvae and larviform females are among those organisms commonly called " glowworms".
This genus is rather close to Pleotomus and its relatives. These were formerly separated as tribe Pleotomini, but appear to be a specialized offshoot of the Lampyrini.
Usage examples of "lampyris".
Shall it find its old place on the shores of the Gulf of Salerno, or shall it mingle its rays with the northern aurora up among the fiords of Norway,--or shall it be borne across the Atlantic and reach the banks of the Charles, where Agassiz and Wyman have taught, where Hagen still teaches, glowing like his own Lampyris splendidula, with enthusiasm, where the first of American botanists and the ablest of American surgeons are still counted in the roll of honor of our great University?
