Golden Birdwing "Troides aeacus" is a beautiful and large butterfly belonging to the Swallowtail (Papilionidae family).

Description

Closely resembles "Troides helena cerebrus" and differs as follows:—
Upper side, "fore wing": the pale adnervular streaks more prominent, in some specimens extended into the cell along the outer half of the subcostal and of the median nervules.
"Hind wing": the cone-shaped terminal black markings in interspaces 2, 3, and 4 more or less broadly bordered on the inner side by a dusky area that is irrorated with blackish scales; the black on the costal margin narrower, not extended below vein 8.

Underside similar to the upperside, but the dusky black borders to the cone-shaped marks in interspaces 2, 3, and 4 wanting.

Antennae, head, thorax, abdomen and abdominal fold as in "Troides helena cerebrus", but the abdomen beneath with two rows of black spots.—

In the female the differences from "cerebrus" are
"Fore wing": the pale adnervular streaks very broad, very prominent and extended well into the cell.
"Hind wing": the basal third of the cell and of interspace 2 black, the middle portion of the latter yellow anteriorly, bufty-white posteriorly ; the posterior half of the discal area between the postdiscal spots themselves and between them and the terminal cone-shaped markings more or less irrorated with blackish scales; lastly, the black in interspace 7 interrupted by an inner triangular and an outer small yellow spot.

Antennae, head, thorax and abdomen as in "cerebrus", but the abdomen beneath with two lateral and two median rows of black spots.Bingham, C. T. 1907. Fauna of British India. Butterflies. Volume 2]
