    Post Arctornis in Singapore.

    After more than a decade there is still no further studies of the Arctornis in Singapore.
    MoB remains the sole reference.
    The white species are very difficult.
    However a few which can be identified can be eliminated from the unidentified list.

    Arctornis singaporensis.
    White, without corrugated scalings.
    No black discal spot.
    Veins green tinged.
    Male ground whiter & the veins stripes less defined.
    Female vein stripes enhanced by interneural bands of white scales,
    The two sexes can look like different species.
    Males.
