    Hi Dr Seow,

    Here to check in a few more skippers to verify their IDs.

    1) Could this be Telicota linna? Underside looked pale but its overall appearance looked weird.

    2) Pelopidas sp.; Very worn not sure if can be ID-ed further.

    3) Pelopidas sp. ; quite large, not sure if this could be P. conjunctus?

    1. Female T. besta.

    If there are dark-dusted veins it is besta. A pale vform. Underside is actually greenish ochreous.

    Hi Dr Seow,

    Would require your assistance to help ID this skipper.

    Pelopidas sp.? No HW cell spot though, and size is 1.5x a P. mathias.

    Thank you!

    Hi Dr Seow,

    Could I check if the following skippers are all Erionota thrax?

    I am unable to visualise the difference between E. thrax and E. torus and would like to seek your assistance to shed light on the differences.

    Thanks for the diagrams Dr Seow! It made the part on wing margins alot more clearer.

    Can I check if the FW spots are diagnostic? I have added additional photos to the photos 2 & 3 for post 76 as the FW spots look kind of different.

    Post 76:

    2) Added a shot showing FW upperside and a more parallel shot of the underside.

    DSC_0984.jpg DSC_0995.jpg

    3) Similarly, added a shot of FW upperside and a more parallel shot of the underside.

    In addition, adding on another Erionota, could this be E. torus then?

    Post 78.

    The shape of spot 3 was given by Flemings, author of BoWM&S.
    It is not absolute. Need to view in the correct perspective.
    You can see the difference in the Yutaka website,

    2 is certain to be E. torus. Corrected.
    3 looks to have the termen a bit straighter, but FW is broad as in E. torus.
    Compare typical E. thraxfemale with narrower FW.
    http://www.butterflycircle.com/check...2012--0060.jpg

    I would include it as E. torus.

    Do note interspecific crosses occur & can be fully fertile with sibling species.

    A. is fairly typical E. torus female.

    Correction

    Some typo errors.

    1 is Erionota thrax.

    2 is certain to be E. torus.

    3 is likely to be also E. torus.
    In a perfectly perpendicular shot the blunt wide angle to the FW is always seen in E. thrax.
