    Post 61,
    Yes. This is a female T. colon.

    Normally in T. colon FW spots 4 & 5 are distorted in shape & in the male they are not aligned, ie spot 5 is farther out from spot 4.
    This is not so obvious in the female.
    In female FW spot 5 is often bisected horizontally as seen here.
    The general appearance is as in T. besta female but besta female have spots 4 & 5 equal & not distorted.

    T. colon male & female.

    Thank you!

    a) Potanthus trachala?

    Abdominal end is black banded, UNF spots 4 and 5 connected by spikes, UNH spots 5 at least strongly projected out and size larger than typical P. omaha.

    Hi Dr Seow,

    For post 63. a), the size of the skipper I shot was not around the size of P. omaha but quite abit larger.

    Not sure if it helps but I have a shot of the upperside as well.

    DSC_0645.jpg

    In additional, I have another Telicota to verify.

    I am hoping it is T. linna.

    Veins with no dark dusting, face and underside of body seems to be quite pale compared to the rest?

    Thank you!

    The upperside shows it is not P. serina.
    The FW veins crossing the band on the upperside of P. serina are strongly darken.
    P. serina.
    https://inaturalist-open-data.s3.ama...6069/large.jpg
    https://inaturalist-open-data.s3.ama...213/large.jpeg

    It is also not going to be P. juno or lydia (a highland species).
    I will leave it as P. mingo as the most likely possibility.


    The second is correctly Telicota linna female.



    TL Seow: Cheers.

    Thanks Dr Seow!

    Could the following be Pothanthus trachala then?

    FW spots 4 and 5 seems to be detached from other spots? UnFW spots 4 and 5 connected by spikes?

    Thank you!
