    Lampyridae is a family of insects

    in the beetle order Coleoptera.

    They are winged beetles, and

    commonly called fireflies or

    lightning bugs for their

    conspicuous crepuscular use of

    bioluminescence to attract mates

    or prey. Fireflies produce a "cold

    light", with no infrared or ultraviolet

    frequencies.

    This chemically-produced light from the lower

    abdomen may be yellow, green, or pale red, withwavelengths from 510 to 670 nanometers. There

    are 2,000 species of firefly found in temperate and

    tropical environments. Many are in marshes or in

    wet, wooded areas where their larvae have

    abundant sources of food. These larvae emit light

    and are often called "glowworms", particularly in

    Eurasia. In the Americas, "glow worm" also refers to

    the related Phengodidae.

    A larviform female showing light-

    emitting organs on abdomen.

    Fireflies also known as glow

    worms, tend to be brown and

    softbodied, often with the elytra

    more leathery than in other

    beetles. Though the females of

    some species are similar in

    appearance to males,

    larviform females are found in many

    other firefly species. Superficially,

    these females can often be

    distinguished from the larvae only

    because they have compound eyes.

    The most commonly known fireflies

    are nocturnal, though there arenumerous species that are diurnal.

    Most diurnal species are non-

    luminescent, though some species

    that remain in shadowy areas can

    produce light.

    Female Photuris fireflies are known

    for mimicking the mating flashes of

    other "lightning bugs" for the sole

    purpose of predation. Target males

    are attracted to what appears to be

    a suitable mate, and are then

    eaten. For this reason the Photurisspecies are sometimes referred to

    as "femme fatale fireflies."

    Light and chemicalproduction

    Many fireflies do not produce light. Usually these

    species are diurnal, or day-flying, such as those in

    the genus Ellychnia. A few diurnal fireflies thatprimarily inhabit shadowy places, such as beneath

    tall plants or trees, are luminescent. One such

    genus is Lucidota. These fireflies use pheromones

    to signal mates. This is supported by the fact that

    some basal groups do not show bioluminescence,

    and rather use chemical signaling. Phosphaenus

    Hemipterus has photic organs, yet is a diurnal firefly

    and displays large antennae and small eyes.

    Firefly systematics, as

    with many insects, are in

    a constant state of flux,

    as new species continue

    to be discovered. Thefive subfamilies listed

    above are the most

    commonly accepted

    ones, though others suchas the Amydetinae and

    Psilocladinae have been

    proposed.

    This was mainly done in an attempt to

    revise the Lampyrinae, which bit by bit

    had become something of a "wastebintaxon" to hold incertae sedis species and

    genera of fireflies. Other changes have

    been proposed, such as merging the

    Ototetrinae into the Luciolinae, but the

    arrangement used here appears to be

    the most frequently-seen and stable

    layout for the time being. Though mostgroups appear to be monophyletic, some

    (e.g. the tribe Photinini) are perhaps

    better split up.
