There are over 2,000 species of fireflies.  The firefly belongs to the insect family of Lampyridae.  Common names for this insect are firefly, lightening bug, or glowworm.  They aren’t actually flies, as entomologists classify them, they are beetles!  Unlike flies, who have one pair of wings, fireflies have two pair of wings, four wings altogether.  The word “fly” is in many insect names, such as firefly, dragonfly, or scorpianfly, but the insects are not true flies and belong to another family of insects. 





Most fireflies are bioluminescent as adults and have the ability to glow.  Bioluminescence means simply light produced by a chemical reaction, which originates in an organism.  All known firefly larvae are bioluminescent, as are firefly eggs.  Not all bioluminescent beetles are fireflies.  There are some related beetle families that have bioluminescent members, such as click beetles (Elateridae), phenogdid beetles (Phengodidae), and several other very small families.
