    Male Ionolyce helicon.


    At certain angle I. helicon looks like N. beroe

    Both species have the innermost costal spot above the mid-cell band absent.



    Ionolyce helicon. Male FW long pointed
    FW postdiscal always serially dislocated at every vein point.
    HW submarginal spots sharp-pointed, particularly in space 3 just above the large black tornal spot in space 2.

    Nacaduba beroe.
    FW postdiscal typically with a mid dislocation, rarely broken at every vein points as in I. helicon.
    HW submarginal spots lunulate (crescentic) not sharp pointed particularly in space 3.
    Males.

    A male in which the HW submarginal spots appear sharp, but it is only the white stria defining the dark spot.
