Restless (Explore & Frontpage)

The butterflies in Thailand seem to be busy all the time and not to rest. I was walking through my father-in-law's garden, trying to get some nice butterfly pictures. This was the only half decent one. Here, the butterflies a lazy bugs compaired to those in Thailand, sitting around pretty often :-) This butterfly was as big as a small bird and the way, it was flying was different from our butterflies.

From Wikipedia: Golden Birdwing (Troides aeacus) has a wingspan reaching about 15–16 centimetres (5.9–6.3 in). In the males the fore wings are black, with veins bordered by whitish colour, while the hind wings are bright yellow. The underside of the wings is quite similar to the upside. The females are larger than the males and have dark-brown or black wings. Head, thorax and abdomen of this butterfly are mainly black, with small red patches on the thorax and a yellow underside of the abdomen. Caterpillars are pale brown, with long protrusions resembling thorns. They mainly feed on Aristolochia and Thottea species (Aristolochiaceae).

Troides aeacus 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.
