Fire Centipede
The so-called "fire centipede" is a name used to refer to any centipede that exhibits bioluminescence. Often nocturnal, bioluminescent centipedes are uncommon and are not associated with any particular habitat.
One fire centipede of repute is widely distributed in tropical Asia and Africa. Known to be the Orphaneus brevilabiatus, the said fire centipede would look something akin to a necklace of precious jewels if one were to come across it on a moonless night.
A certain chemical substance secreted by the fire centipede produces this bioluminescence. The light appears to come from the secretions of two luminous patches near the ends of each segment of the centipede's body. The source of the light is beneath the body of the insect and can be made out through the exterior.
Another centipede that glows in the dark is the Geophilus electricus. This fire centipede is long and yellowish in color. Other than centipedes, millipedes also glow. Endemic to the Sierra Nevada of California, the species of millipedes designated as Luminodesmus sequoiae is known to emit light at night. From the moment they hatch, these millipedes glow. The source of their light is embedded in the deeper layers of their integument. Their luminescence is continuous, with no voluntary control.
Larval fireflies may be misconstrued as fire centipedes. The mistake is a result of the propensity of fireflies to precociously exhibit bioluminescence. Fireflies in their larval phase radiate a single, unwavering light on their foreheads.
