    There are several species of Leucania (formerly Mythimna) of wide distribution & rather simlar.

    The FW here has a white apical streak . a series of postmedial black dots, a black streak along the lower cell arm.

    L. loreyi is widespread (Africa, Europe Asia & Australia) but has a white discal dot.

    L simillima comes closes & has a black discal dot, but its known distribution does not include here yet.
    A good match for this Taiwan specimen.

    L. nabalua is said to be very similar (Its distribution now include HK.)

    I would place it as Leucania cf. simillima. meaning it is close to simillima & may be it.

    A moth with a unusual abdomen sighted today at the Club. A Deidamia sp, Sphingidae? Please help ID, Dr Seow.

    At first there seems no match for this in wingshape, markings or those abdominal growths.
    A cross-check ,however, indicates only one candidate is possible.

    Morwennius decoratus. abnormal, with developmental defects.

    By rotating the FW sideway it is possible to match most of the markings although distorted or altered.
    The FW apex with a window & thumbprint mark is correct.
    Even the dark medial patch is matched, brown in this case.
    The wingshape is severely distorted & it is doubtful if it can fly properly.
    The abdominal outgrowths may be tumours or parasitoid cocoons arising from the airholes or spiracles.

    PS. I see this is actually a Pyralid ,Terestia.
    I have the assumption this is a large Sphingid.
    I was so focused on Sphingid I failed to realise the head & posture are typical Crambid/Pyralid.
