    Default Chiangmai 7-12 Oct 2019

    I went for a short trip to Chiangmai, 7-12 Oct 2019, with sifu Khew, Cheng Ai and Jonathan. It was a short but fruitful trip, 4 full days of butt hunting/shooting. It was the first Chiangmai butterfly trip for Cheng Ai, Jonathan and I, and there, we met up with Antonio and his lovely wife, Kai.

    I will be posting photos of the butterflies that I shot at Chiangmai and Chiangdao...trying my best to ID them, appreciate inputs and corrections if there is/are any...

    I will start of with Hesperiidae, Hesperiinae, interestingly, the speicies there are much nicer than those that are found in Singapore.

    Ochus subvittatus (Tiger Hopper)

    This tiny one was the first hesperiidae that caught my attention, with a wingspan of only 22mm (if I'm not wrong).







    Thoressa masoni (Golden Ace)




    Aeromachus stigmata (Veined Scrub Hopper)




    Sovia albipectus (Silver-Breast Ace)




    Thoressa cerata (Northern Ace)

    For the last one, think it is Lesser Band Dart (common name in HK), Potanthus trachala.

    There are about 20 species of Potanthus species in Thailand & their IDs can be very difficult from fieldshots.


    Potanthus no. 1; Male on the left ,female on the right.
    Male abdominal end not black-banded ,FW spots overlapping HW spot 6 absent; Female FW spots no overlap between spot 5 & 6; HW spot 6 present.
    Underside dark shaded.

    Three species have the abdominal end yellow without a black band. namely P. omaha, ganda & confucius.

    P. omaha ;HW band the veins dark-dusted, shading light.
    http://www.butterflycircle.com/check...obby%20Mun.jpg

    P. ganda; HW band the veins not dark=dusted ;heavier dark shading.
    P. ganda is normally quite oranging but it difficult to judge in fieldshots.
    Male from P. Malaysia; female from Singapore.

    P. confuciusFW spots broadly overlapping; HW underside usually with spot 6; Band edged with definite dark spots.
    Male Thailand female from Taiwan.

    No. 1 should be Potanthus ganda.
    You can see the the respective sexes match.



    2. FW with spot barely overlap spot 3 while spot 5 is detached from spot 6. FW spot 2 & 3 wider.Abdominal end with a black band.
    This should be P. pseudomaesa.
    Examples.

    Similar.
    P. lydia;
    FW spot 4 & 5 often convergent on their inner margins.; FW cell more heavily dark.
    https://www.ifoundbutterflies.org/me...07a03494-1.jpg
    http://www.samuibutterflies.com/02_i...huslydia.r.jpg

    P. serina ;FW spot 5 distinctly smaller than spot 4; HW with a small spot 6 on inner corner.
    https://singapore.biodiversity.onlin...96bb1e9322.jpg

    P. palnia; FW spot 5 smaller than spot 4; band more strongly divided by dark veins.
    https://farm5.static.flickr.com/4566...3350f458_b.jpg

    P. trachala have the FW band uniformly narrow & the outer margins strongly excavated.
