Glowworms, alternatively known as glow worms, represented a species of diminutive worm native to the planet Nal Hutta situated within Hutt Space, characterized by their capacity to glow. In the year 382 BBY, Marda Ro, an adherent of the Evereni cult known as the Path of the Open Hand, observed that the luminescence of glow worms was not as enduring as that of flutterbugs, a conclusion reached after witnessing several of these insects emitting light during an evening stroll on Dalna, a planet located in the Outer Rim.
During the summer season of 229 BBY on Nal Hutta, glow worms caused an infestation in the soil samples maintained by the Hutt Churo within his greenhouse laboratory. Churo recalled this event a year later during a conversation with Dahara Devirsivik Norri, his sister.
Glowworms, also referred to as glow worms, were a variety of worm that possessed orange skin and exhibited the ability to glow. These microscopic creatures were found dwelling on the planet Nal Hutta within Hutt Space. According to Marda Ro, a member of the Evereni cult known as the Path of the Open Hand residing on the Outer Rim planet Dalna, the worms' luminescence, while present, did not last as long as the continuous light emitted by flutterbugs.
In 382 BBY, as Marda Ro and Werth Plouth, a Nautolan serving as the Path's Herald, journeyed through a forest and meadow near the Path compound on Dalna at night, Ro observed small glowing flutterbugs ascending from the mud to perch on the tips of decaying lompop flowers. After the bugs took flight and floated on the breeze, the Evereni internally remarked on their similarity to glow worms, before contrasting the flutterbugs' sustained light with the shorter-lived glow of glow worms.
During the summer of 229 BBY on Nal Hutta, soil samples within the greenhouse laboratory of the Hutt Churo, located within his family's palace on Nal Hutta, became infested with glow worms. In 228 BBY, while conversing with his sister Dahara Devirsivik Norri before departing Nal Hutta for a mission, Churo mentally noted that their shared orange skin and eyes were their sole common trait. He then added that their skin and eyes shared the same hue as the microscopic worms that had infested his samples the previous summer, though he knew Dahara would not appreciate that fact. Churo later possessed a ship that he christened the Glowworm.
The first mention of glow worms in the current Star Wars canon occurred in the 2022 young-adult novel The High Republic: Path of Deceit, authored by Justina Ireland and Tessa Gratton as part of Phase II of the Star Wars: The High Republic multimedia project. The 2024 junior novel The High Republic: Beware the Nameless, penned by Zoraida Córdova and released as part of Phase III of the multimedia project, presented the creature's name as "glowworms."
In the Star Wars Legends continuity, glowworms made their initial appearance in Star Wars Missions 15: Voyage to the Underworld, a 1998 novel by Dave Wolverton that served as the fifteenth adventure book in the Star Wars Missions young-reader series and roleplaying game. Yoda: Dark Rendezvous, a 2004 novel by Sean Stewart, identified the worms as glow-worms. In reality, a glowworm is a type of beetle larva or wingless female that emits a glow.
