(PhysOrg.com) -- There are more than 2,000 species of fireflies around the world, many of
which are best known for their bioluminescence. Fireflies, which are
not flies but beetles, produce flashes of light in order to communicate
with each other and to attract mates. The color of light emitted by the
luceferin molecule in fireflies can range from red to yellow to green.
However, the chemical and physical origin of firefly color variation is
not well understood.
