Charaxes jasius is a medium to large butterfly with a wingspan reaching 65–75 mm in males and 75–90 mm in females. The uppersides of the wings are dark brown with orange margins. The hind wings bring two short tails, characteristic of most species of the genus. Close to these tails there are a few blue markings. The underside of the wings is reddish brown with numerous darker bands edged with white or gray. The orange marginal band is also present on the undersides of the wings and it is preceded by a white transversal band. The caterpillar is green, cylindrical and has two yellow ocelli on the back. The head bears four horns facing backwards. The adults prefer ripe fruits, of which they suck the sugary liquids. Charaxes jasius has two generations per year: the first in May–June and the second in August–September. After the second it spends the winter in the larval stage, to flicker the next spring. The female lays the eggs on the upper surface of the leaves of the host plant, laying no more than one egg per leaf. The larva make a kind of "bed" by silky wires, on which it returns promptly after feeding on surrounding leaves. Then they hang on a twig and pupate. After a period that can range from two weeks to one month, the pupa opens letting out the butterfly. This species occurs in the Mediterranean region and Africa.
