    On this note, i would like to inquire how do i differentiate Caltoris philippina and Polytremis lubricans?

    Im still relatively new at IDing skippers and these two gives me a very hard time. Both shares similar colouration and course scaling,and i feel that from pictures the spots seem to appear in the wings of both species as well

    Would like to inquire how can i learn to differentiate both

    Regards

    Male Pantoporia sandaka sandaka .

    The two species are much confused.
    In Singapore P. hordonia have become very rare.

    P. hordonia hordonia.
    FW grey submarginal band at least 2X wider than orange band & nearly that in the female.
    Male postdiscal spot in space 2 with a narrow 'foot' running along the lower margin.
    In female this end more abruptly.
    Males in P. Malaysia.

    Females.
    Probable female Singapore.

    There is a tendency for the orange to become obsolete.

    P. sandaka sandaka.
    FW grey submarginal band usually narrower than the orange band, sometimes constricted.
    In female the grey band is wider & can be as wide as the orange band causing confusion.
    Male postdiscal spot with a long large foot tapering in along the lower margin.
    HW with a white speculum sometimes shown as a white highlight below the FW.
    Males in P. malaysia.

    Mating pair from NE India.
    Note male at bottom with wider orange submarginal & large foot of the FW postdiscal spot is identifiable as P. hordonia.
    The female on the top have submarginal grey band as wide as the orange band & could be mistaken for P. hordonia.
