    Male Nacaduba berenice. Correction : Nacaduba hermus.

    The two smaller 6-line blues, N berenice & calauria can sometimes be difficult to ID.
    There are probably hybrids causing intermediates.

    N. caluria; FW postdiscal band almost always straight, & unbroken.
    There should not be any dislocation ie. breaks in the white striae forming the margins of the band.
    FW only submarginal spots 4 & 5 pointed, somewhat triangular or haert-shaped.
    All valid examples.
    Pairs male on the right.

    N. berenice.

    Variable. Typically some dislocation of FW postdiscal band ,usually mid at vein 4 or at vein 3 or 5.Also often rather crooked.

    Dear Dr Seow,
    There's only four line, probably should be Nacaduba pactolus odon instead of berenice? Thanks.

    Oops!
    I was too preocupied with 6line blues.Once I opened the answer box, I can not see the image again until I finished the reply.

    This is Nacaduba hermus.
    Resembles N. sanaya but the FW postdiscal band is generally unbroken, & there is always some metallic blue scales in the HW tornal black spot.

    N pactolus looks similar but HW submarginal spot 6 is very angular , while the rest of the submarginal spots form a narrow regular band, a very distinguishable feature. White striae are also enhanced.
