    Dear Doctor Seow,

    Here are some past observation that i need require some assistance on. I find it tough to sort through these, and im still using the moth of borneo website to sort out even just at family level.

    1 - Noctuoidea
    inat link - https://www.inaturalist.org/observations/153800854

    2 - Genus Ericeia
    inat link - https://www.inaturalist.org/observations/151401882

    3 - Subfamily Herminiinae
    inat link - https://www.inaturalist.org/observations/150483095

    4 - Eumelea sp (i consider myself lucky it let me took a shot even, their perching angle is horrible all the time)
    inat link - https://www.inaturalist.org/observations/152705398

    5 - im not sure where to start with, but it has two distinct spots
    inat link - https://www.inaturalist.org/observations/124871238

    6 - Acropteris genus - what a pristine specimen, at that!

    5. Organopoda perobata.

    Two species have very large HW spots & also a white spot on the FW.

    O. cnecosticta have the FW antemedial wavy.

    6. Acropteris rectinervata.

    Two species are very similar.
    ACROPTERIS.png

    Acropteris rectinervata is much commoner.
    The veins in both sexes are normal & straight.
    The white marginal band is almost uniform in width, only slightly wider at the apex.

    https://singapore.biodiversity.onlin...doptera-000382
    https://inaturalist-open-data.s3.ama...249/medium.jpg


    Acropteris grammearia.
    The veins in the female are normal & straight.
    In the male thw veins are closer in the middle, curving out to the margin.
    The white marginal band is more abruptly widen at the apex.
    https://www.mothsofborneo.com/part-8...niinae_2_1.php
    See Acropteris species 1 for A. rectnervata & Acropteris sp. 2 for A. grammearia.

    A. grammearia.
    https://www.thaibugs.com/wp-content/...eris%20sp2.jpg

    Only two observations suggest A. grammearia (female)

    3. Chusaris species.

    These two are likely to be the same species except one is more heavily darken.
    https://www.inaturalist.org/observations/150483095
    https://www.inaturalist.org/observations/150483098

    There is no match with Bornean materials but this Taiwanese species is very close.
