This work depicts a man on a sleeping mat protected by Wamidai (plant medicine) from attacks from small bloodthirsty burrowing insects. Wamidai refers to a purplish flower found near shoreline mangroves on several islands. In past times, women who were gathering food would also collect the little flowers and place them under the family sleeping mats before dark. The flowers stop 'Bak', a small bloodthirsty burrowing insect, from coming up from the ground and biting people who were asleep. When the insect smells the flowers, it is driven away like a repellent. This medicine was used for hundreds of years and ceased in the 1800s when missionaries brought alternative methods of insect control.
