The Southern Festoon (''Zerynthia polyxena'') is a striking butterfly belonging to the family Papilionidae of butterflies. Its flight time is from April to June in a single brood. == Description == The Southern Festoon (''Z. polyxena'') can reach a wingspan of 60–80 mm. The females have slightly longer wings, usually lighter colored than males. The basic color of the wings is yellow, but they have a complicated pattern of several black bands and spots. On the edges of the hindwings they have a series of blue and red warning spots to deter potential predators. The body is dark brown and bears red patches on the sides of the abdomen. This butterfly can be confused only with the Spanish Festoon (''Z. rumina''). The differences are in the presence of blue on the hind wings of ''Z. polyxena'' and the relatively lower amount of red on its forewings as compared to ''Z. rumina''.

They are initially black, then they are yellowish with six rows of fleshy orange and black spikes all over the body. They feed on birthworts (''Aristolochia'' sp.), mainly (''Aristolochia clematitis'' and ''Aristolochia rotunda''). The special food of the larvae provides the toxic substances which then also go to the adults, making them inedible.
