The obvious answer would be a firefly. But that is the only bioluminescent insect I know. Sorry
By the mixing of two chemicals called 'bioluminescence'.
The molecule originally discovered to cause bioluminescence in fireflies was dubbed Luciferin.
The light produced by bioluminescence uses the energy from a living organism. Bioluminescence occurs in marine animals, such as loose-jawed fish of the genus Tomopteris; bioluminescence also occurs in land animals, such as the glow worm and the firefly.
bioluminescence is earths most important source of light tru or false
bioluminescence
The female lightning bug uses her glowing tail to attract a mate.
That would be the worm and the love bug, one of the most famous worm-like infections
Shakespeare uses the word "bug" to mean a bugbear (this is a word Shakespeare also uses), a spook, a bogeyman (a word which derives from "bug"), something to frighten children. In a famous early-sixteenth century version of the Bible, Ps. 91 is translated "Thou shalt not need to be afraid for any bugs by night." The KJV substituted the word "terror". Shakespeare uses this word only five times, perhaps most characteristically in A Winter's Tale: "Hermione: Sir, spare your threats: The bug which you would fright me with I seek."
Bug control, elimination, and relocation are uses of bug spray. Sprays may be used to get bug populations within limits acceptable to concerned property owners and smooth-functioning food webs, to leave no trace of them in areas of concern, and to motivate them to move out of sensitive living, play and work spaces.
Click beetles and fireflies are both bio luminescent. Click beetles are equipped with two menacing "false eye-spots" on the thorax, and many are more than 1-1/2 inches in length. Tropical relatives of the big-eyed click beetle are called fire beetles and have bioluminescent eye-spots. One, Pyrophorus luminosa, produces "cold light" that is green and red, and is as bright as that of the more familiar fireflies. Its larvae, called glow-worms, also produce light.
"Bioluminescence is the biochemical emission of light by living organisms such as glow-worms and deep-sea fish..."
Most outlets that have an aisle with bug sprays.
