Species of moth
Psilogramma argos is a moth of the family Sphingidae. It is known from Western Australia, the Northern Territory and northern Queensland.[2]
Adults have long, narrow pale grey wings, with black markings. The abdomen is grey, with no dark dorsal line.
The larvae feed on Gyrocarpus americanus. They are green with a strong curved horn on the tail pointing backwards, a series of diagonal white stripes on the sides and dark marks on the back of each segment. Full-grown larvae are about 80 mm long. Mature larvae leave the food plant and forms a cell of silk under the soil in which pupation takes place.
