    They are both Telicota besta male.

    Do not be confused by the colour in photos as much depends on the white balance.

    Here is a review.

    T. colon male :FW spots staggered, ie not in line; spots 4 & 5 often distorted.

    T. bambusae .I am unsure if this occur in Singapore.
    Continental specise but feed on common grasses such as rice, bamboo, maize & sugar cane.
    Small species FW 15mm, compare with T besta 17-20mm.
    FW spots 4 & 5 equal .FW short & spots wide; HW veins not darken.face paler.

    Hi Dr Seow,

    Would require some help with the IDs.

    1. Telicota besta?
    aaaa.jpeg

    2. Is it possible to ID with just the upper wing shot? Did not get a chance to shoot the undersides. Size wise, it was quite large, definitely larger than the typical Pelopidas. Could it be Pelopidas assamensis?
