Its called bioluminescence. Light production in fireflies is due to a chemical reaction that occurs in specialized light-emitting organs, usually on the lower abdomen. The enzyme luciferase acts on luciferin in this organ to stimulate light emission. This reaction is of scientific interest.

this is because the fireflies have certain genes that codes for an enzyme luciferase.this enzyme converts the substrate luciferin to oxyluciferin.during this reaction some heat is liberated so this flies glows during night

The possible reason is they are looking for mates. Being visible in the dark can help mates find them.
But it also attrack predators.

I think lightening bugs (fireflies) light up because of the phosphorus ( a chemical) in their body.
