papalotl (Mdz20v)
This is an iconographic example of the warrior outfit called the papalotl, which means butterfly. It is identified in Berdan and Anawalt's The Codex Mendoza (1992, vol. 1, Appendix F). The body covering is primarily turquoise, with red trim at the neckline and white cloth or feathers over the groin area. The prominent butterfly features include the antennae that curl to the right and left off the top of the headdress and the yellow stylized wings coming off the circular central piece. The antennae are yellow and turquoise. The headdress also has red feathers shooting straight up from the top of in a fan-like arrangement, with other colored feathers (yellow, green) at the base. The center of the main, circular device has a red ring and yellow feathers pouring out of it.

Given the turquoise color of this particular outfit, rather than simply a papalotl, this may be a xiuhpapalotl, which is a symbol that dates back to Teotihuacan (the Classic Period). See Ian Mursell's study of the meaning of butterflies in Aztec culture. He also explains how butterflies were "a symbol of fire, war, paradise, flowers, heroes, of the souls of warriors who fell on the battlefield or in human sacrifice, of women who died in childbirth."
The use of red and yellow at the center of the butterfly may be suggesting access to the interior of the insect, but this is just conjecture. See the essay about the use of red and yellow. For a pre-Columbian ceramic butterfly stamp with a circle on its abdomen, see the one at the Metropolitan Museum of Art.
