The sandfly, alternatively written as sand fly or sand-fly, was a type of insect belonging to a species that lived on the planet of Tatooine. These sand flies were known to perch on moisture vaporators, create a buzzing sound within the damaged edges of pourstone structures located in the settlement of Anchorhead, and dwell within caves situated in the desert. These insects were a source of annoyance, flying around and bothering banthas.
The existence of sandflies was initially documented within the Star Wars novelization released in 1976. The instructions for the Star Wars video game from 1991 referred to the in-game insects as "Flying Insectoids," however, an associated guide featured in Nintendo Power magazine utilized the designation "Sand Flies." Subsequently, the sand fly was referenced in The New Jedi Order: Vector Prime, a novel penned by R. A. Salvatore in 1999. Further mentions occurred in the 2011 novels The Old Republic: Deceived and Riptide, both of which were authored by Paul S. Kemp.
