    Some honourable mentions before I post the pièce de résistance

    1) The immaculate Troides andromache were present on all days, and the females, with almost entirely ash-grey forewings, were just spectacular. None provided any shooting opportunities, despite the numerous nectaring plants that seemed to be growing around...

    2) The nominate Trogonoptera brookiana ssp. brookiana. As above with Troides...see but no touch.

    3) On one day I saw a very unusual butterfly that was entirely new to me show up at the puddling site. It, however, never stayed, and I only saw it land for a split second. But the sight is burned into my brain, and I can't seem to identify it. Here's the description: A nymphalid, about the size of a Dichorragia, or a slightly larger Stibochiona; flight powerful and very erratic, just like Dichorragia; body and wings entirely black and unmarked, sans for a white dot on the tip of the forewing, much like Rohana, but behavior, size, and biology described as above ^. I want to believe its a Stibochiona, and the only Bornean endemic I can think of is S. persephone, but a photo of it is not available online. Aaron, or Dr. Seow, if you're reading this and if anything you know matches the description, i'd be interested in hearing your thoughts.

    4) The unique and peculiar Amnosia decora showed up on the first day. Both sexes were seen flying about and ducking under leaves. I didn't get any good shots.

    5) At a sunlit patch of forest created by a fallen tree, I saw, in the canopy, a myriad of amazing lycaenids just absolutely living their best lives. Jacoona, Neocheritra, Drupadia, Neomyrina, and the other usual long-tailed canopy dwelling lycaenids were to be found. I saw amongst the mix what I could have sworn to be Iraota abnormis. It was fairly large, white on the underside with some speckling of brown; flight was very territorial and purposeful. Alas without a picture, it will only remain a myth.....


    which brings me to this!


    Poritia plateni


    Poritia plateni

    Poritia plateni! Another "book species", and perhaps my best find so far (second only to Hypochrysops coelisparsus I posted some years ago). I found this freshly eclosed female fumbling down a tree like a moth, before resting on a very lofty blade of grass on a vertically inclined slope. For this I had to balance with one hand gripping onto a clump of vegetation, while climbing up the slope, and with my other hand stretched a full 180 degrees with my 2.5 kilogram camera gear. I had to use my tongue and fingers on one hand to change ISO settings! Needless to say sorry for the slightly out of focus shot, but I dare say what a find!

    Sabah turned out way better than I had hoped.

    Sounds like Stibochiona schoenbergi to me, which would have been very exciting. The male is almost entirely black. The female looks like this


    Very nice collection of endemics and nice shots of P. plateni, which is endemic only to Palawan and Northern Borneo. Makes me wanna revisit Sabah again!

    I'm thinking some of the Theclines you mentioned could have been Ticherra staudingeri or T. acte staudingeri which is a very beautiful species/subspecies endemic to Kinabalu

    You do have the elusive Stibochiona persephone.

    The original description by Staudinger is in German.
    https://archive.org/stream/deutschee...e/451/mode/1up

    Roughly translated, the male is deep black with a white short spot not far from the margin at the apex, white dots on the fringes (?cilia)& two vague blue spots in the middle cell of the forewing.

    It is amazing this is so rare that there are no images on the net.


    TL Seow: Cheers.

    PS. In Lepindex the taxon (taxonomic name) persephone is placed as a junior synonym of schoenbergi

    There is an image of Stibochiona schoenbergi but it is nothing like the original description of S. persephone.

    I recall reading (but i can't rmb where) that persephone and schoenbergi are different sexes of the same species. D'abrera nicely shows the dimorphism but unfortunately i don't have it at hand at the moment

    Thanks guys! It is nice to see my claim of seeing S. persephone in the wild being supported by the literature! Persephone is an interesting character in Greek mythology, being tricked by Hades in becoming his wife as ruler of the underworld. Very fitting for a species so dark and elusive.

    You are right. Staudinger described the female in the 2nd part as ' have brownish yellow wings with a burnt chrome yellow strongly violet band in front of the outer edge of the hindwing...etc.'

    Accordingly S. schoenbergi is the valid name & persephone is a junior synonym.


    TL Seow: Cheers.

    Thanks for sharing Lemon - wonderful shots and some very interesting butterflies you have found
    Will keep Mahua Waterfalls in mind.
