    Default Assistance to ID Hesperiinae Shot at Northern Thailand

    Dear Dr Seow,

    Please assist to help ID these butterflies. I have tried to ID by comparing against Antonio's checklist and pictures found on the internet.

    Pic 1: Could this be a Large-spot Plain Ace (Thoressa hyrie)?

    Pic 2: Could this be a Moore's Ace (Halpe porus)?

    Pic 3: Could this be a Overlapped Ace (Halpe arcuata)?

    Pic 4: Could this be a Common Bush Hopper (Ampittia dioscorides)?

    Pic 5: Could this be a Moore's Ace (Halpe porus)?

    Pic 6: Not sure what this is?

    Pic 7: This butterfly is rather big. Looks like an Awl.

    Thanks for your help again. Hesperiinae are really hard to ID.

    6. Thoressa hyrie.

    Pithauria murdava looks similar; Large size, sharper FW;FW subapical 6 much larger than spot 7 ; HW pattern different.

    7. This is rather worn ;The orange tip antenna suggest Thoressa or Pithauria.
    The underside seem to have a series of spots.
    In particular a large spot 6.
    I think it is the female P. stramineipennis.


    TL Seow: Cheers.
