Males of all Agrias species have prominent yellow tufts of androconial scales on the hindwings.These disperse pheromones for attracting suitable mates.
Erythroxylum species are food sources for the larvae of some butterflies and moths, including Dalcera abrasa, which has been recorded on E. deciduum, and the species of Agrias.
"They are very robust insects, measuring four inches across the wings, which are broad and dentated, with the tip of the fore-wings much produced, but not falcate, the hind-margin being oblique and then nearly straight below; near the inner-margin of the hind-wings of the males stands a yellow tuft of stiff hair (androconial tuft), as in Agrias.
