    You have two different species here.
    This often happens when skippers flit in & out of view in the bushes.

    Very large with sweptback FW.
    Antenna appears wholly black .(pale area very weak in Baoris).
    Abdomen with more noticeable bandins.
    Often HW underside may have a pale area at the cellend.

    2. Female probably Pelopidas agna.
    Note this individual have a tear in the right FW & a crumpled left FW.
    There is a tiny spot just below spot 2 (the largest spot).
    This is seen in only three species. Correction: a 4th sp. Caltoris philippinafemale also have this extra spot but it lacks the cellspots.
    Male & female of Pelopidas assamensis.( Excluded by FW spots large & white & white-banded antennae.)

    Females of P. mathias & agna.

    The individual is rather worn
    The UnH is plain brown.
    P. agna is also a larger species.
    These two features suggest female P. agna.



    TL Seow: Cheers.
