Five or more, see text Agrias is a genus of Neotropical charaxine nymphalid butterflies found in South and Central America.

Some of them, like the famous A. sardanapalus, having been first discovered by Bates in the Amazon Valley, are of an absolutely charming beauty, and the contrast of its purple-red forewings beaming through a blue lustre hued over them as if in a violet purple gloss, with the brilliantly sapphire-blue hindwings, is undoubtedly one of the most magnificent sights that nature has ever produced in the whole world of butterflies.

The species of the genus Agrias have, variously, very bright red, orange, iridescent blue and yellow colouration contrasting on the black or bluish background of their upperside wing.

The larvae are pale brownish, marked with lichen-green spots, have recurved "horns" on the head capsule and a bifid tail.

During the dry season, strong-flying A. amydon undoubtedly forage in open areas, only to return to sheltered retreats in response to thermal stress.
