Kiltiks were massive, beetle-esque omnivorous creatures native to Cathar. They dwelled in colonies comprised of numerous guard kiltiks and a solitary, significantly larger queen kiltik. These creatures were nocturnal, remaining dormant during daylight hours and emerging from their nests in vast numbers at night to forage. Their feeding habits led to the desertification of large portions of Cathar, prompting Cathar warriors to conduct regular ritualistic blood hunts aimed at eradicating their nests. A complete kiltik nest was once destroyed by the Sylvar.
It is speculated that they possibly became extinct around 3963 BBY, a period when Cathar suffered immense destruction at the hands of the Mandalorians during the Battle of Cathar. However, this extinction has never been definitively confirmed, raising the possibility of hidden underground hives.
