    Dear Dr. Seow, Can please confirm if both are Notocrypta paralysos varians. Seen in Penang Hill on August 11, 2023. Thanks.

    Thanks Dr. Seow,
    Need to clarify. You mentioned N.clavata white band reached margin by extra spot, that is for this photo, right?

    Normally the white band reaches the margin broadly on the underside in N. clavata, in both sexes.
    The female may have an extra spot joining the band to the margin on the upperside.
    The male white band always fall short of the margin on the upperside.
    See the single female from Ranong.
    http://yutaka.it-n.jp/hes/91610010.html

    The ID of N. clavata is based on the white band broadly reaching the costal margin on the underside.


    TL Seow: Cheers.

    Thanks for the noting the differences on upperside and underside and gender differences of this species. Hopefully, I can encounter this species again and take more photos on both sides. This one was just basking in the morning and then flew off. Appreciate your helpful info.
