This is a medium-sized swallowtail. The wings have narrow tails and a broad white band across a black background. The submargin of the hind wing is marked with large red spots that likely mimic the rose red markings of Parides ascanius. This species also has a red streak on the underside of its wings, which its model (P. ascanius) does not have.

life history

This species depends upon the habitat adjacent to the swamps where its model species (P. ascanius) may be found. Its primary host plant is Annona acutiflora.


Known from a single small site in extreme eastern coast of the state of Rio de Janeiro in Brazil.  The site also contains an abundance of endemic plants making it a high conservation priority.


Habitat destruction has extirpated this butterfly from all but one known site in southeastern Brazil, which itself is now threatened by development and removal of trees for firewood and grazing cattle.

conservation needs

The one site where it occurs, as well as important host plant and nectar sources, need to be protected.
