* ''VideoGame/HollowKnight'': Lampposts can be found throughout Hallownest that are topped with glass spheres holding small, glowing insects (this despite all characters in the game being much larger anthropomorphic insects). If the glass is broken, the insects flutter away. [[spoiler:The BigBad, Radiance, is a much darker example, being the [[LightIsNotGood evil goddess of light]] whose influence spawned the Infection. As shown when you use the Dream Nail, bugs under the Infection's thrall are {{Mind Rape}}d to insanity, only barely able to muster up enough sentience to ramble about the Radiance's light.]]

* ''WesternAnimation/AvatarTheLastAirbender'': An inventor in one episode uses jars of lightning bugs as illumination in a natural gas fissure. His lack of eyebrows attests to why.

* ''WesternAnimation/DespicableMe'': Briefly used as a gag when one Minion uses another as a glowstick, bending his cylindrical body to make him glow.

* In ''Literature/Mermaid2011'', the Sea Queen lights her palace with bioluminescent fish.

* ''Literature/MermaidsSong'' has an undersea version. The merfolk use caged bioluminescent fish to light their homes.

* ''VideoGame/HollowKnight'': Lampposts can be found throughout Hallownest that are topped with glass spheres holding small, glowing insects (this despite all characters in the game being much larger anthropomorphic insects). If the glass is broken, the insects flutter away.

* In ''WesternAnimation/TheLittleRascals'' episode "Rascals' Revenge", Buckwheat's flashlight is essentially a jar full of fireflies attached to a stick.

* ''WesternAnimation/DawnOfTheCroods'', taking place before the [[WesternAnimation/TheCroods invention of fire]] has the characters using [[MixAndMatchCritters hybrids of deer and fireflies]] as flashlights.

** ''WesternAnimation/RobinHood'': A fishbowl of fireflies hung from a fishing pole is used as a way to trick Prince John into thinking that Robin Hood (disguised as a gypsy fortuneteller) can speak to spirits.

There's some TruthInTelevision, but only as a fun activity for little kids, as they're tiny, short-lived bugs that only glow at a certain time of day during a select period of the year; you'll need to constantly resupply the jar with food for the bugs; it will take dozens of them to make a feasible light source.

* ''Series/UltramanAce'': One episode have Ace dealing with a firefly monster, Hotarunga ("Hotaru" literally meaning firefly in Japanese) whose powers include a tail-light capable of discharging electricity, which knocks out and nearly defeats Ace in the peak of battle. The light in its tail can also fire a CaptureBeam allowing it to imprison humans.
