firefly or lightning bug, small, luminescent, carnivorous beetle beetle, common name for insects of the order Coleoptera, which, with more than 300,000 described species, is the largest of the insect orders. Beetles have chewing mouthparts and well-developed antennae. ..... Click the link for more information. of the family Lampyridae. Fireflies are well represented in temperate regions, although the majority of species are tropical and subtropical. They are nocturnal in their behavior, and males commonly fly about in the evening during early summer. In many species the females are wingless. Males, females, and larvae emit a heatless, greenish-yellow to reddish-orange light; in some species even the eggs glow. The light, believed to play a role in sexual attraction between the adults, is produced by light organs located on the underside of the abdomen. These consist of several layers of small reflector cells and a layer of light-producing cells. The light-producing cells are permeated by nerves and air tubes; oxygen supplied by the air tubes converts the cell product luciferin to oxyluciferin. This oxidation, catalyzed by the enzyme luciferase, releases energy in the form of light. The insect controls the emission of light by regulating the amount of air supplied to the cells. The intensity and frequency of the flashes vary with the species and probably serve to identify males and females to each other. Synchronized flashing is characteristic of some tropical species. Adult fireflies of many species do not feed. The larvae, which hatch from eggs laid on or in wet soil, feed on snails and earthworms, injecting their prey with a paralyzing fluid. Pupation (see insect insect, invertebrate animal of the class Insecta of the phylum Arthropoda .

Asian glowworms are considered beneficial controllers of crop-damaging snails and slugs. There are other luminescent insects, including members of other beetle families; the most spectacular are found in the click beetle click beetle, common name for members of the widespread beetle family Elateridae.

Adult fireflies are 0.2–1 in. (5–25 mm) long and have light-producing organs on the underside of the abdomen. The soft, flattened, dark-brown or black body is often marked with orange or yellow. Some adult fireflies do not eat; others feed on pollen and nectar. Most fireflies produce short, rhythmic flashes in a pattern that is characteristic of the species and an important mating signal. A software-based media server for Windows, Mac and Linux that shares iTunes, M3U and PLS playlists to DAAP clients across the network. Noted for the variety of formats it supports, Firefly handles MP3, AAC, WMA, Ogg-Vorbis, FLAC and Apple Lossless audio files. Formerly called mt-daapd (multithreaded-DAAP daemon), Firefly uses Bonjour to announce itself over the network. See DAAP, Bonjour and playlist. |

| Ye guardians of the Pepper Chamber,** now No longer young to him, the firefly flits Through the black hall where, lost to love, he sits, Folding the veil of sorrows round his brow, Unto a life which I call natural I would gladly follow even a will-o'-the-wisp through bogs and sloughs unimaginable, but no moon nor firefly has shown me the causeway to it. |
