Mimoides Phaon

''Mimoides phaon'', the red-sided swallowtail or variable swallowtail, is a species of butterfly in the family Papilionidae. It is native to the Americas.

Description

The dorsal side of the red-sided swallowtail's wings is variable. They are mainly black with the hindwings having a postmedian band of spots, which are either greenish blue or red. Some individuals have one or two rows of smaller light colored spots along the outer margin of the hindwing. The forewing has a row of whitish spots along the outer margin, which may be reduced or lacking in some individuals. The underside of the wings is less variable than the upperside. The outer margin of the hindwing has a row of small red crescents. The basal area of the hindwing, the thorax, and the head are spotted with red. The abdomen has a row of lateral red spots, which distinguish ''M. phaon'' from other members of its genus.

Description from Seitz

P. phaon Boisd. Similar to the preceding species 'Mimoides protodamas''">Mimoides_protodamas.html" ;"title="'Mimoides protodamas">'Mimoides protodamas''; the spots on thorax and abdomen red, the
posterior abdominal segments with red lateral spots. Very variable. Spots on the upper surface of the forewing bluish yellow-grey or purer white -yellow; discal band of the hindwing grey-blue, rarely red. Under surface without distinct cell-streaks, forewing without basal spots, hindwing with 3. Scent-scales present in the male. Mexico to West Ecuador and Venezuela. The following forms have been described as species: ab. loc. ''xenarchus'' Hew., hindwing with broad red band; ab. loc. ''eridamas'' Reak., the red band of the hindwing narrow, the spots composing it separated; these two forms only known from East and South Mexico ; ab. ''phaon'' Boisd. (I3b), forewing with submarginal spots, but without discal spots, the band of the hindwing just entering the apex of the cell; ab. ''ulopos'' Gray (= ''immarginatus'' Oberth), forewing without spots or with only indications of them, band of the hindwing broad, entering more or less far into the cell; ab. ''therodamas'' Feldr., with discal and submarginal spots on the forewing and narrow, slanting band on the hindwing, separated from the cell; ab. ''metaphaon'' Butl. has on the hindwing a very large blue-green discal area, occupying a good part of the cell; in ab. ''pharax'' Godm. & Salv. the hindwing has a red anal spot and the discal band is remote from the cell. All these forms are connected with one another by transitions. Seitz, A. ed.
