Banded Swallowtail

Papilio demolion

The Banded Swallowtail is a species of swallowtail butterfly found in Asia.
Papilio Demolion - Banded Swallowtail Like most paps, not easy to get close enough for a clean shot.

BUT, when you do, what a nightmare. The lateral wing strip is a very pale green, but when you get back to the lab, the stripe is inevitably white. This is because the butterfly is predominantly black, which means that the camera metering system tries to make the black into a grey and lengthens the exposure, which in turn, washes the subtle green strip out to white.

On the next opportunity, you remember this, and adjust the exposure compensation to one stop under. Of course, this gives a problem with the black, but I believe the stripe feature is what counts in this case. I could probably do something clever with Photoshop by masking the stripe and lightening the rest - pfft!

Location is Bandung, West Java, Indonesia. Alongside a stream and paddy fields.

Appearance

Male upperside brownish black. Fore and hind wings crossed by a broad prominent oblique pale greenish or yellowish-white band that commences just before the middle of the dorsal margin of the hind wing, crosses over on to the fore wing and is continued as a series of spots that diminish in size in the upper interspaces to the apex of that wing; on the hind wing this is followed by a subterminal series of similarly-coloured lunules. Underside fuliginous black, the transverse band that crosses the wings as on the upperside. Fore wing: cell with a series of four slender longitudinal pale lines from base; the veins also picked out with pale lines; on the veins that run to the terminal margin these lines are conspicuous only at the apices; there are besides short similar lines between the veins that extend to the terminal margin. Hind wing: the interspaces beyond the transverse medial greenish-white band marked with broad jet-black streaks up to the subterminal line of greenish-white lunules; these streaks medially interrupted by a transverse line of blue scales and succeeded in interspaces 1 and 7 by preapical ochraceous-yellow spots; terminal margin beyond the line of lunules black.
Antennae, head, thorax and abdomen fuliginous black; beneath, the palpi and abdomen greenish white, the thorax dark grey.
