Eupanacra busiris is a moth of the family Sphingidae. It is known from Malaysia (Peninsular, Sarawak), Indonesia (Sumatra, Java, Kalimantan, Sulawesi), Nepal, north-eastern India, the Andaman Islands, Myanmar, Thailand, southern China, Vietnam and the Philippines. Probably also in Sri Lanka.
The wingspan is 68–82 mm. Adults of ssp. busiris have a vivid green colour on the upperside of the head and thorax and a characteristic green area on the forewing comprising a broad costal band with a lobe extending towards the hind margin. In the other subspecies the colouration is duller. The distal margin of the forewing is deeply sinuate. The hindwing is narrow and the costal margin is clearly dilated near the base. The upperside of the head and thorax is green. The forewing upperside has a green space between the antemedian and postmedian lines, contrasting with the rest of the wing.
Adults are on wing from late March to late August in Hong Kong. They fly at dusk and are attracted to the flowers of Duranta erecta.
The larvae have been recorded on Lasia species and Pothos scandens in India.
