The Riorians represented an insectoid race. In 4 ABY, Loje Nella, an individual of this species, attended a show by the Max Rebo Band which took place at Jabba's Palace.
Initially, Riorians were designed for the 1983 movie, Star Wars: Episode VI Return of the Jedi. The Riorian seen in the film was a puppet, controlled by Mike Quinn, and the creature designers at the Industrial Light & Magic Monster Shop internally referred to it as "Toadstool Terror".
