Attacus taprobanis is a moth of family Saturniidae. It is native to southern India and Sri Lanka. This species is very similar in morphology to the much more widely distributed Attacus atlas. It was once considered a subspecies of A. atlas.
Attacus taprobanis is much darker than A. atlas. The hyaline spots are small and narrow. The hyaline streak on the forewing is absent. The wingspan about 170–220 mm, probably the second largest after A. atlas. In males, the forewings are maroon, sickle shaped, and smaller than the females'. The wings are fairly dark reddish brown. The lateral band is clearly pink but with little white vanes transparent stains are narrowly triangular in the male, large and teardrop shaped in females, the forewings, there is also a fairly narrow, tiny spot in front of the store.

The larvae feed on various bushes and trees. Adult moths do not take foods and survive on fat they have stored from their larval period. The females sitting most calm and emit pheromones, that the active males can notice from a distance.
