Eupanacra metallica
Eupanacra metallica is a moth of the family Sphingidae first described by Arthur Gardiner Butler in 1875. Distribution 
It is found from north-western India across Nepal, Bhutan, Bangladesh and northern Myanmar to south-western China. Description 
The wingspan is 60–73 mm. It is similar to Eupanacra sinuata, but the upperside ground colour is more orange and the lines on the forewing upperside have a different trajectory. Furthermore, the forewing underside is less brown and the basal area is paler. There is a broad, buff band on the hindwing upperside, while the hindwing underside is largely buff with hints of brown. Biology 
The larvae feed on Arisaema tortuosum in India.
