Rioxa is a genus of tephritid (fruit flies) in the family Tephritidae.[1] The genera Rioxa and related Hexacinia and Cribrorioxa are distributed in South and Southeast Asia from India and Sri Lanka in the west to the Philippines. Only a few species extend east of Borneo to New Guinea and the Bismarck Archipelago. Rioxa breeds on fallen logs inside forests.[2]
Male Rioxa sexmaculata display on suitable fallen logs with bark beetle holes by inflating pleural vesicles at the base of abdominal segment 5 and raising their abdomen and walk in circle around a spot. They are thought to exude pheromones which attract females. After copulation the male guards the female which lays its eggs in the holes made by bark beetles.[3]
