As a result, depending on the bioluminescent chemicals it creates, each variety of glow-worm emits a slightly different hue.īioluminescence is seen in many different species in nature, ranging from mushrooms to fish. The structure of the molecule determines the wavelength emitted. When ATP gives these molecules’ energy, they slowly release it at a precise wavelength. This molecule is a protein that is triggered by ATP in the case of many insects. The structure of certain biological molecules allows them to absorb energy from a variety of sources. Glow-worms are an excellent starting point for learning about several very essential biological processes! Glow worm Bioluminescenceīiological molecules absorb energy and emit it as light, which causes bioluminescence. Glow-worms are intriguing organisms thanks to the biological principles that enable them to survive. Other species may be enticing mates, warding off predators, or attracting other insects to aid in the spread of the fungus they consume. Bioluminescence is used by certain animals, such as the Arachnocampa, to attract and collect insects. Other “glow worms” are just the larval stages of certain beetles.Įach species of glow worm may have developed its bioluminescence for very different reasons, and they may not even be related. Fungus is a food source for several Fungus Gnat species (as their names suggest). Unlike Arachnocampa worms, however, not all glow-worms consume other insects. While they are the most well-known and well-known glow-worms, many other insect species create a glowing light while they are in their larval stage. Each trapped bug is simply reeled into the mouth of the larval glow worm and food is served! This species’ larvae grow into huge flying insects.

Insects always get tangled when they fly into the tangled mess of sticky fly-traps.

(This is why the genus name “arachno” means “spider.”)Įven little spots of light may attract a large number of insects in the dark tunnels where these insects reside. They release light from their abdomens, which is supposed to attract insects thanks to bioluminescent chemicals in their bodies. These insects are incredible in that they dangle slime threads all around their nest. When people say “glow-worm,” they usually mean a genus of Fungus Gnat (Arachnocampa) that glows blue or green when in the larval stage. Glow worms pose species from four distinct beetle families, as well as fungus gnats from many genera.

Glow worms are enthralling creatures! In reality, “glow worm” is a popular term for a variety of insect species that use bioluminescence to shine.
