单词	firefly
释义	firefly /ˈfʌɪəflʌɪ / noun (plural fireflies) A soft-bodied beetle related to the glow-worm, the winged male and flightless female of which both have luminescent organs. The light is chiefly produced in flashes and typically functions as a signal between the sexes. Family Lampyridae: many species, especially in the tropics, and including the European Luciola lusitanica. Later lab experiments showed that by flashing an artificial light at a firefly you could speed up its rhythm, you could slow it down, make it flash a little later than it would otherwise.... We were guided as we went by millions of fireflies whose flashing marked the banks like landing lights on an airstrip. The firefly's light is only visible for an instant.
