    Hi Dr Seow,

    I would like to seek confirmation that the following are Pelopidas mathias?

    I based it on the paler wing margins on the right individual and the general more grey-ish appearance.

    Thank you.

    These are typicak Pelopidas mathias, the male on the right is more strongly grey-tinged.
    The grey gives P. mathias a dirty look.

    P. agna.

    Correction.

    Post 14. no. 5.
    Probably Caltoris bromus female.
    The antenna do not match that of Polytremis lubricans.
    Male P. lubricans in the same posture for comparison.
    https://inaturalist-open-data.s3.ama...815/large.jpeg


    Female Caltoris bromus often have a spot in HW space 2 & 3 ,sometimes one in space 2.
    Caltoris bromus Taiwan male & female.
    https://encrypted-tbn0.gstatic.com/i...jBFQg&usqp=CAU
    https://encrypted-tbn0.gstatic.com/i...gKvlg&usqp=CAU


    There appear to be a single hyaline spot in HW space 2. seen only in C. bromus female here.

    Baoris lack the ochreous overscaling & the antenna is mostly black.

    1) Caltoris sp.? but I do not see pale area on the antennae.
