About Macroglossum corythus Walker, 1856
Macroglossum corythus Walker, 1856 has a wingspan of 50 to 66 millimeters. Its overall coloration varies slightly between subspecies and across the climates of different countries. The head, thorax, and abdomen are rufous in color. The distal segments of the abdomen lack lateral black marks, and the tips of the anal tufts are ruddy. All lines on the forewings are obsolescent, with the postmedial lines less bent than typical; the forewing markings are reddish and ill-defined. The hindwings have a narrow, pure yellow band. The larva of Macroglossum corythus is dark violet brown with dorsal specks. A subdorsal yellow line occurs on the 2nd, 4th, 10th, and 11th somites, and the larva's horn is long and tuberculate. In later larval stages, yellow and olive-brown transverse dorsal lines and yellow lateral spots develop. Larvae have been recorded feeding on species in the Loganiaceae and Rubiaceae plant families. The pupa is bone-colored, with a black dorsal stripe on the frons and thorax.
