A swarm of sand lice are shown here, covering some of Luke Skywalker's food supplies while he was on Beheboth. The sand louse refers to a diminutive insect species that populated dry and sandy locales, most notably desert regions. These creatures were typically viewed as nuisances due to their habit of contaminating both food and water sources, rendering them unfit for eating or drinking. Tatooine and Beheboth were two planets where they were known to exist.
