What are lightning bugs?

They are soft-bodied beetles that are commonly called firefliesglowworms, or lightning bugs. They make use of their bioluminescence during the twilight (right before dark, but after sunset) hours 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.

Where can they be found?

They can be found in temperate and tropical climates, which is why you will most likely see a few in your backyard. Many can be found in marshes or in wet, wooded areas where their larvae have abundant sources of food. While all known fireflies glow as larvae, only some adults produce light.

Fireflies Life Cycle

Fireflies undergo a transformation called complete metamorphosis. A few days after mating, the female will lay her fertilized eggs on or just below the surface of the ground. The eggs will then hatch three to four weeks later, and the larvae feed until the end of the summer. The larvae are commonly called glowworms. The term glowworm is also used for both adults and larvae of species.

How do lightning bugs create light?

Light production in fireflies is due to a type of chemical reaction called bioluminescence. This process occurs in specialized light-emitting organs, usually on a firefly’s lower abdomen. All fireflies glow as larvae. In lampyrid larvae, bioluminescence serves a function that is different from that served in adults. It appears to be a warning signal to predators since many firefly larvae contain chemicals that are distasteful or toxic.
