    Probably Pelopidas mathias.

    Pelopidas mathias.

    Although P. mathias & agna appear to be common in Singapore there is a lot of mixedup with these two species.

    Pelopidas mathias.
    Male UpF spot 2 & 3 quadrate or at least broad
    A line thru the two cellspots cut the brand.
    Ground colour grey-tinged ,often giving a dirty uneven shading, darkish around the spots, paler along the margins..
    FW cilia darkish compared to the paler HW cilia. Added important clue.

    Pelopidas agna.
    Male UpF spots 2 & 3 narrow especially spot 2.
    A line thru the 2 cellspots usually bypass the brand.
    UnH uniform brown clear, with a greenish tinge (usually not seen in fieldshot).
    FW cilia as pale as HW cilia but edged blackish. Added important clue.

    Males with upperside confirmation.

    Many observations, but mostly poor quality singleshot views which make ID difficult.
    Many IDs of P. agna but most are doubtful.
    This shot is undoubted but the UnH view is poor. Note uniform brown UnH.
