    Thanks Dr Seow for the explanations!

    Would this then by P. omaha?

    Would you consider the veins in this photo to be dark dusted?

    Thanks!

    Yes. I would say they are P. omaha.
    At least the HW veins continue as dark dusted crossing the marginal zone, to the margin.
    Ideally the upperside HW would be available for confirmation.
    Perhaps some gene introgression (hybrid element) in the male.
    The female is more obvious comparing with typical P. ganda females.
    P. ganda.

    Hi Dr Seow,

    Seeking your assistance to ID the following skippers. As the forum seemed to not be functioning properly for me on web, please access the iNat links to view the photos.

    Thank you!

    1) Telicota besta? as there seemed to be dark dusting on HW wings.

    https://www.inaturalist.org/observations/181036284

    2) Pelopidas agna?
    uniform brown colour and larger than P. mathias.

    https://www.inaturalist.org/observations/181539431

    3) Telicota besta?
    Quite orange but based on the male brand drawing it seemed to resemble more to T. besta.

    https://www.inaturalist.org/observations/181539441

    4) Pelopidas sp.

    Initial impression is P. conjuctus but the FW spots doesnt look to be much larger than HW spot? So probably P. agna?

    https://www.inaturalist.org/observations/181539446

    5) Pelopidas agna?

    Uniform brown and larger than typical P. mathias.

    https://www.inaturalist.org/observations/181539447

    6) Pelopidas mathias?
    Dirty mix of grey and brown.

    https://www.inaturalist.org/observations/181539453

    7) Telicota sp.

    Rather orange but probably leaning towards T. besta.

    2. Caltoris bromus male.

    Three species have more prominent pale areas on the antennal shafts.

    Caltoris bromus
    FW typically with two large subapical spots ;upper cellspot also large.
    HW dark brown & nearly the same tone as FW.
    Female paler, with HW spots 2 & 3.
    Male.
    https://www.inaturalist.org/observations/163945647
