Rhagastis lunata

Rhagastis lunata, the lunulate mottled hawkmoth, is a moth of the family Sphingidae. It is known from Nepal, north-eastern India, Thailand, south-western China and Vietnam.
The wingspan is 72–86 mm. The antenna are longer and thicker than in all other Rhagastis species, except Rhagastis gloriosa. The forewing upperside has a characteristic bluish-white submarginal line formed of crescent-shaped marks, the horns of which are directed basally. Both wings are pinkish-red, with traces of the ochreous ground colour distally. The black basal area of the forewing is reduced to a streak or patch behind the discal cell. The hindwing upperside has a well-defined orange-beige median band, including a series of vein dots.
