The reclumi spider was a type of arthropod that originated from the Mid Rim planet known as Null. This particular spider variety possessed the ability to create webs with sufficient strength to halt a vehicle in motion.
During the year 22 BBY, the Jedi knights Anakin Skywalker and Obi-Wan Kenobi were in pursuit of a suspected assassin believed to be responsible for the death of Samish Kash. Anakin, while piloting a commandeered swoop, inadvertently flew into one of these webs, resulting in the loss of their target.
