    Hi doctor Seow,

    Ive shot a few other moths since they kind of flutter around as butterflies as well, and i challenge myself making some IDs here. I would like to seek ur advice, but shall u think its insufficient, i am more than happy to have it left as a genus ID, since i dont think i will be dissecting moths anytime soon. My reference are generally singapore publish articles and inat links, since i lack any moth reference book, which i will be buying soon(if you can recommend any titles i would appreciate it!). I refer to inat as well, even though the species suggestion isnt the best its at least a effort i can carry out

    1 - Prosopandrophila distincta. My ID reach this conclusion base on a few past documents, such as https://lkcnhm.nus.edu.sg/app/upload...nis385-392.pdf and general ID on inaturalist. The caterpillar in the general ID observation feeds on the same plant as the pdf attach, which i induce which is why it is the species i suggested. Since i lack any of the moths reference books, this is my best attempt as such, from comparing pictures of physical specimens. This specimen is about the size of a general bushbrown, shot at seletar area

    2 - Cyclosia macularia. This specimen was likely ran over by a bicycle at sembawang PCN, and was dead. I suspect the yellow stuff poking out are her eggs(how sad! she didnt manage to complete her lifecycle purpose). The glossy reflection of the wing scale is a nice colouration however, even in death. I refer to https://lkcnhm.nus.edu.sg/wp-content...nis151-158.pdf as my reference and general inat link

    3 - pseudosesia species. I couldnt find any information about pseudosesia species in Singapore, and i use to think they are part of the burnet moth family until i found out they are from Sesiidae family. Ive concluded these two fine specimen are males due to the coremata in one of the observation. I have shot a pseudosesia in the past before i am extremely interested in bugs, so i added a old photo of a potential female ive shot, which was also in the same area. A interesting note is that they seem to always appear at leea indica patches for the nectars and appears to also just rest around the area in general. However, i cant find any online articles about their lifecycle, and the australia article https://www.researchgate.net/publica...acific_Islands here, i am afraid it might be irrelevant

    Post 5.

    1 & 2 are right.
    If you dont have any references, here are a few.

    Moths of Borneo covers about 75% of the macromoths in Singapore.
    Zygaenidae is in vol. 2.
    https://www.mothsofborneo.com/
    Addendum; It seem vol. 2 is not accessible on line. You have to purchase the hard copy.


    Moths of Thailand Noctuidae vol. 3 ocvers 50% of the Noctuidae in Singapore.
    https://www.researchgate.net/publica...ra_in_Thailand


    Of the smaller moths, Pyralids of Borneo covers many of the Crambidae & the Thyrididae.
    http://www.pyralidsofborneo.org/index.php?overview


    I think the Sesiid is incorrect.
    Try the BOLD (Barcode of Life Database)inventory.
    https://v3.boldsystems.org/index.php...page?taxid=503

    Without some clue you have to go through both subfamilies to tribe to genus & species.
    eg tribe Paranthrenini.
    https://v3.boldsystems.org/index.php...?taxid=1066647

    It is too tedious.
    Good luck.


    TL Seow: Cheers.

    This one have been identified by a moth specialist as Pseudosesia rufifinis.(rufifinis= red end.)
    It is the same species ,but without the yellow patches on the thorax.
    https://guatemala.inaturalist.org/observations/78287533


    TL Seow: Cheers.
    PS. The same specialist has named your current observation as just Pseudosesia ssp.
    So it is best to leave it as such.
    https://www.inaturalist.org/observations/118123724
    PS2.
    Walker's original description as Sannina rufifinis based on a male from Sarawak.
    https://archive.org/details/journalo...p?view=theater
    Kallies' uploaded images fig 161-162.(images labelled wrongly?). Possibly 160 is P. rufifinis, & 161,162 are T. andrepiclera.
    https://www.researchgate.net/figure/...fig9_343697577
    PS3.
    Based on this related species, the one with the yellow patches on the thorax is the female.

    I noted one of your observation is misIDed.
    https://www.inaturalist.org/observations/136413206

    This is Ugia disjungens.

    Three species are very similar & easily confused, namely U. disjungens, Hypospila bolinoides, & Tochara creberrima.

    Ugia disjungens.
    FW postmedial slightly oblique,at the apex it curved out to the apical tip.
    Discal spot is oblong or reniform (kidney-shaped).
    Antemedial is crenate (scalloped).


    Hypospila bolinoides.
    FW postmedial about parallel to the margin, set deeper than in Tochara, ending at the costa.
    Discal spot is rounded.
    Antemedial is absent.


    Tochara creberrima.
    FW postmedial is parallel to the margin ,nearer to it than in H. bolinoides.,& ends on the costa.
    Discal spot is reniform
    Antemedial is absent.

    Dear Doctor Seow,

    Another challenging ID i require some assistance and second opinions with. I was inform by the general community that this is a brunia species, but another user has challenge my current thoughts when photos of a similar looking species, Katha prabana, was shown to me. I know its extremely difficult to narrow by species, so if genus or family is the next best alternative, i am willing to take a look! These are all inat post since the photos have been archive, hope it doesn't cause any inconvenience.


    This are the following observation by me. I will accept that theres a chance they are different species.
    https://www.inaturalist.org/observations/136413222
    https://www.inaturalist.org/observations/118122190

    But here lies two more challenging ones i need assistance with, and these are caterpillar only observations. Most Singapore reserves closes by 7pm and thus night surveys are hard to be conducted for moths survey. Here are two caterpillar which i notice are somewhat seen from time to time, but do not have proper identification. Both are IDed as Kunugia species, but i do not have access to any literature material that might be of proper ID records. Would like your second opinion here.
    1-caterpillar with two red horn. No doubt it is a lappet moth, and overtime this has been ID'ed as Kunugia caterpillar.
    https://www.inaturalist.org/observations/137035498

    2-Massive caterpillar. Easily 10cm. Not has hairy nor furry but extremely big size.

    Dear Doctor Seow

    Akin to my previous skipper post, i also have some moth clarification for today. I have no clue for the moths so any suggestion will do

    1 - inat link - https://www.inaturalist.org/observations/143999359

    2 - Trichaetoides chloroleuca? or amata stellaris?
