    I think this should be a female D. rufotaenia as well, Khew.

    The key states for D. ravindra the orange band does not reach beyond halfway into space 1b, whereas this have bits of orange to about vein 2.

    Perhaps in the past most females were mistakened for D. ravindra.

    Uncle Seow,
    I believe this one I shot is a female too.
    The palpi seems quite long and a large portion is dark.

    Maybe it should also be added that in rufotaenia, the hindwing verso space 6(near the extreme edge of the wing) is heavily black-dusted, such that it is predominantly black with virtually no orange. Forewing verso postdiscal black lines more clearly delineated.

    In ravindra(at least of those in the checklist), this area has relatively more orange suffusion. Forewing verso postdiscal black line usually somewhat incomplete.

    This feature seems to be consistent among those in the checklist.

    Surprisingly C&P4 does not mention this trait.

    You are right Brian. It is a female Common Posy.

    Aaron, this has been mentioned in the earlier posts in a different way.
    It is quite consistent with the male rufotaenia.
    However, there are variations & overlaps especially with the females of both species, as the examples given earlier.

    When I enlarged the image to 200% I can see orange to vein 2, so I am quite confident your Posy is also a female D. rufotaenia.

    I managed to locate one other image from the web apart from yours, also from Singapore.
    The wingshape is distorted & the black hook appeared elongated, but the orange extend to vein 2 & there are bits of orange to vein 3.

    Here's two for comparison.
    Both were shot at the same location but at different days of the month and both were equally small.

    Great shots, Nelson.

    The male is typical D. rufotaenia.

    The female is quite interesting.
    1. There is a large difuse marginal spot in space 6 as in the male.
    2. The hook band has a shorter point.
    3. The hook band & the straight discal band touch at the dorsum as in the male rufotaenia.
    4. There are bits of orange along the black tornal line to vein 3.

    I believed there are more than sufficient clues to indicate this is the female D. rufotaenia.

    How difficult is it to separate the females of the two? Here is one of the female ravindra linked earlier.
    It also has a diffuse marginal spot in space 6, but the hook band has a longer point, and on enlarging there is no trace of orange beyond halfway into space 1b (ie none to vein 2 or 3).
