Androgeus swallowtail

Wing span:

Identification: This species is sexually dimorphic. Males are dark brown with a hook-shaped yellow band on the outer postdiscal and subapical regions of the forewings, and a yellow band on the postbasal and discal regions of the hindwings. The hindwings also have yellow submarginal lunules at the scalloped termen and a tail at the tornus. There are two additional rows of lunules on the underside of the hindwings, on the inner side of the submarginal lunules, one blue and one red. Additionally, the forewings have small yellow submarginal lunules on the underside. There are also thin yellow stripes radiating from the base of the forewings to the inner side of the broad yellow band. The body is dark brown at the head and thorax and yellow at the abdomen. Females are dark brown with a faint iridescent green tint on the forewings, excepting the margins, veins and cell, and a bright iridescent green tint from the base to the outer postdiscal region of the hindwings. One of the lunules at the tornus is red instead of iridescent green. The hindwings also have two rows of iridescent green submarginal lunules at the scalloped termen and a tail at the tornus. The iridescent green tint is not present on the underside of the wings. Similar to males, the hindwings have three rows of lunules on the underside, one yellow, one blue and one red, and the forewings have small yellow submarginal lunules.
