    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.

    Post 13.

    It is likely to be correct as Katha prabana.

    The female of many lthosina are very similar & confusing.
    Brunia antica occur in Hong Kong & Taiwan as the sole species in the genus.
    Thus these are confirmed images.
    https://www.inaturalist.org/guide_taxa/352227
    http://dearlep.tw/species.html?namecode=343836

    The females of Brunia antica & sarawaca are practically identical & it is uncertain if B. sarawaca is present since images of males taken in Singapore do not quite match .
    https://www.zobodat.at/pdf/ENT_0038_0141-0176.pdf


    Salient points.

    Female of Brunia antica & sarawaca; Top of head & prothorax yellow.

    Female of Katha prabana. Top of head & prothorax dark grey as the rest of the thorax.

    BRUNIA.png



    Taxon probana was first described as Eilema probana. later transfered to Katha & now to Dubatolova.

    Katha probana male.
    https://www.inaturalist.org/observations/6740796
    Female.
    http://v3.boldsystems.org/index.php/...e?taxid=588636
    Other examples of the male.
    http://virtualcollections.naturalsci...sa-tams-1935-1
    https://www.researchgate.net/figure/...fig1_267642363


    The main doubt is if the female Katha prabana seem rather common in Singapore, why is the male not being photographed.


    I will leave caterpillars alone as there is very little literature to refer to.



    TL Seow: Cheers.
    PS Brunia antica is rare in Singapore.
    Male & Female. (Probably forelegs should always be dark in antica .)

    Dear Doctor Seow,

    Just one observation here. I shot this adorable green moth with very amazing camouflage. I narrowed down the genus to be eboda, i would like to hear your opinions or second opinion on this observation. Appreciate any form of inputs!

    There is hardly any literature on Eboda.
    It is probably Eboda smaragdinana (= emerald-green) the most widespread species from Sri Lanka to PNG.

    Dear Doctor Seow,

    i am browsing through inat and one genus of moth has gotten my attention due to its frequency of appearing in my favourite butterflying spots. This genus is Ischyja, which seems like a cute moth version of a archduke. I have notice inat and in the context of Singapore, there are 6 species, but i think the 4 which i think seems to be more credible are as follows
    -Ischyja manlia (a example of Singapore, inat link - https://www.inaturalist.org/observations/131083611)
    -Ischyja marapok (https://www.inaturalist.org/observations/3866489)
    -Ischyja hemiphaea(https://www.inaturalist.org/observations/65329917)
    -Ischyja inferna (https://www.inaturalist.org/observations/100292744)
    -Ischyja manlioides (https://www.inaturalist.org/observations/109445389)

    Would like to know if you have any literature that u can share about how to differentiate some of the species here, which i am keen to learn slowly! If there is none, ill still appreciate the insights i am able to get. Hoping whatever little literature on moths will assist in IDs and all

    Thanks!

    Ischyja is an interesting genus of large moths.
    There are at least seven species in Singapore.

    The males can be Ided with some confidence but the females can be very confusing.
    Note wingshape is not reliable in fieldshot ID,and it is hard to judge the HW blue band in partially covered shots.
    I will follow Holloway's descriptive terms.
    ISCHYJA.png



    I will start off with the three easiest.

    1.Ischyja ferrifracta.
    FW apex bisected by a pale ochreus wedge mark.
    https://www.mothsofborneo.com/part-1...neousi_3_3.php
    Female.
    https://inaturalist-open-data.s3.ama...6050/large.jpg


    2. Ischyja anna. Correction: The three images here are not exact images of MoB's I. anna. All 3 could be forms of the female I. marapok.
    2nd Correction: All three images are actually females Ischyja anna.
    FW light grey brown with dark lines forming the medial pattern.

    https://inaturalist-open-data.s3.ama...460/large.jpeg
    Female.
    https://static.inaturalist.org/photo...6517/large.jpg

    Similar but not recorded in Singapore.
    I. hageni ;FW loop mark ovate & marginal zone with veins darken.
    https://www.mothsofborneo.com/part-1...neousi_3_2.php


    3. Ischyja hemiphaea.
    Male with a mid break of the boundary between the darker basal & the paler marginal zones, with 3 spots adjacent to it.
    Female boundary well defined with pale edgings. Reniform spot rounded.
    FW submarginal fascia prominent, dark contrasting & forming a large patch at the apical costa, its margin extending sharply to the tip

    Ischyja inferna & manlioides.
    HW blue band wide in both sexes.

    I inferna.
    Male reniform irregular & parallel to the boundary.
    Loop mark with thin highlights & is separated from the reniform by a dark bar on its upper side.

    I. manlioides.
    Male with the irregular reniform merging with the broad highlight on the outer margin of the loop mark.


    The females of the two are nearly identical.
    Females with diffuse boundary & basal zone dark, the markings hardly visible.
    Holloway states both sexes of I. manlioides have a better defined less diffuse boundary.



    4. Ischyja inferna.
    https://www.mothsofborneo.com/part-1...neousi_3_4.php
    Males.
