Parvinoths were non-sentient insects found throughout the Outer Rim Territories, including the forested planet Ashas Ree. While on a supply run in 34 ABY, the siblings Kel and Eila followed a swarm of the creatures to the entrance of Ashas Ree's Temple of the Force, entranced by their beauty.
The species' delicate wings enabled parvinoths to fly harmlessly through a world's breezes, sometimes in swarms.
While visiting Ashas Ree on a supply run alongside other residents of the supertanker fuel depot Colossus in 34 ABY, the siblings Eila and Kel were entranced by a dazzling parvinoth in the planet's outpost. When they commented on its beauty, the creature maintained the siblings' attention as it joined a swarm of the creatures. The pair decided to follow the insects to a nearby Temple of the Force as they flitted through the air, with Eila leaping in the air to try and catch one.
Colossus resident and spy Kazuda Xiono was frustrated upon finding the children had wandered off and chased them to the temple's entrance, noticing the swarm of parvinoth dispersed as he approached. Despite Xiono's protests, Kel and Eila followed a single parvinoth into the structure. As the creature flew upward to a gap in the roof, then later downward toward the temple's entrance to the Sith temple below, the group's attention was drawn to several symbols carved into the ground.
Parvinoth first appeared in "The Relic Raiders," the seventh episode of the second season of the animated television series Star Wars Resistance. Prior to the episode's release on November 17, 2019, they were included in a season trailer released on August 14 of the same year. Parvinoth were first identified by name in the corresponding episode guide for "The Relic Raiders." Lucasfilm Animation artist Colas Gauthier made a concept illustration of the creatures titled "ashButterflies" on June 15, 2018.
