Parides echemon is a species of butterfly in the family Papilionidae.

[1] P. echemon resembles the preceding species [lysander]; but the forewing is narrower, the outer margin being incurved in the male, straight in the female, the cell of the forewing is narrower at its extremity, the 3. radial of the hindwing is usually much nearer to the 2. radial than to the 1. median, and the fold of the hindwing in the male has no white wool.

— Hubner's figures agree with the form from the Amazon: in the male echemon Hbn.

From Obidos to the Rio Negro, north side of the Amazon; Guiana.

— Whilst P. lysander is a swamp species and flies heavily over the wettest places in the shade of the woods, P. echemon prefers drier localities in the woods, and is often found on the flowers which hang down from the trees over the narrow paths in the forests.
