    Could be...It doesn't look like a match. But, I can't find anything that does match perfectly. Nice find! Posted 5 years ago, modified 5 years ago

    Hi Matt, even though there are yellow forms of the Catacanthus incarnatus, this certainly is not that species or genus (look at the shape of the scutellum for one thing). Also, you talk about "little stinker" and Cat.inc. is not so little :o)
    This looks sufficiently close to the Australian Amyotea hamata to asume at least the same genus, but we would need to do some looking/asking around to get to species I suppose...
    Cheers, Arp

    P.S. David Rider has a list of know species in the genus:
    https://www.ndsu.edu/faculty/rider/Pentatomoidea/Genus_Asopinae/Amyotea.htm
    This page from the Shanxi Agricultural University (China) has images for all species in the genus:
    http://nxy.sxau.edu.cn/info/1584/3204.htm
    The page also references a new species (Amyotea lata) that is a synonym for Amyotea malabarica, according to Salini (2016):
    https://www.researchgate.net/profile/Salini_Santhamma/publication/317801161_Redescription_of_a_predatory_stink_bug_Amyotea_malabarica_Fabricius_1775_Hemiptera_Pentatomidae_Asopinae/

    Hmmm ... not an exact match either ... maybe something else after all ... I'll ask around a bit ...     Posted 5 years ago, modified 5 years ago

      Very interesting Matt - I'll add the other images to the description for convenience of further searching. For now I'm a bit stuck and out of time, so I'll ask some other people if they have better ideas ... Posted 5 years ago

      Hi Matt,
      David Rider kindly and swiftly responded to me nagging him with this that it is a bug in the genus Hyrmine and probably Hyrmine sexpunctata. This is a highly variable species (as is already shown from your two photos!) with a number of other describes species later synonymized as variants or subspecies.
      From the old catalogue by Kirkaldy (1909) I've distilled this list of species in Hyrmine:
      Hyrmine chlorina (Stal, 1858) [Sumatra, Java]
      Hyrmine dispar (Westwood, 1837) [New South Wales]
      Hyrmine minor Breddin 1900 [Sumatra]
      Hyrmine sexpunctata (Linneus 1758) [Moluccas, Salawati, Waigeo, Murua]
      ~ with various named subspecies/variants:
      - ssp. bimaculata (Montrouzier, 1855)[=var montrouzierana Kirkaldy]
      - var. glaucomelaena [=Pentatoma glaucomelas Montrouzier 1855]
      - var. nigrifascia [Rhaphigaster nigrifascia Walker 1867]
      - var. hemichloris [Vulsirea hemichloris Vollenhoven 1868]

      As you can see, Hyrmine sexpunctata is the only species in that list recorded from Papua New Guinea, but of course that was 1909(!) Currently H. sexpunctata is also known from the north east of Australia (probably came over from Papua) and even has two images on the internet (that I didn't find without the name):
      https://www.inaturalist.org/taxa/711877-Hyrmine-sexpunctata

      So far I didn't find any info on the other species being present on Papua (yet). I'll try to find some more literature on the various species over the next days, but for now I'm quite satisfied to ID your images as Hyrmine sexpunctata       Posted 5 years ago, modified 5 years ago

    Impressive that you found all that. There are other colors on that tree. Some all green. I’m going to try to document them all. Am I able to add more than one picture to a write up , or just you all? Posted 5 years ago

      Matt, you can add as many pics as you like. When they are identified as the same species, they will automatically be grouped as such.

      By the way, best to use the "reply" link below a comment, otherwise that other person will never see your comment.       Posted 5 years ago

      Hi Matt, personally I would certainly like to see as many colour variants as possible - especially some green ones, as some of the other species were also originally described based on green specimen. Most of the old descriptions are quite wanting in detail, so it will be really hard to get my head around the visual appearance of these species, as there are hardly any images around. When the museum in Leiden opens again I may try and see what they have to further my understanding a bit for comparison. I'll send you a personal message next with some questions about locality etc.
      Cheers, Arp

      P.S. Apart from the extra photos you may be adding being identified as the same species and having them come together in the species account you may also add the appropriate tags under each image, but also you can add them to the "description" section under this here image, same as I did for the other two new ones. That will make this image and description with the discussion in the comments a nice starting point for future reference.
      Maybe have a look at these "topics" for comparison:
      Coccinella miranda - Larva Some six years ago (or some such - around 2013-14 probably) I was browsing the internet to find images of Green Lacewings found on the Canary Islands (a project with results later published in a paper by Mendes) and stumbled on an image of a ladybird larva taken on Gran Canaria (Sardina), that I just couldn't get my head around.<br /> The old discussion is here on Flickr:<br /> https://www.flickr.com/photos/lagrimon/8325871614<br /> Note that I have notified the author that this is indeed Coccinella miranda and NOT Coccinella algerica, as listed currently.<br /> You may imagine my total exhilaration when I found this 'exact same' larve at a "mirador" in the clouds up in the mountains of La Palma (no view to enjoy, so what better to do than look for little critters :o)<br /> Even though I found it on the same herb together with a few Coccinella miranda adults I could still not quite believe that this would be a Coccinella larva (all the Coccinella larvae I know really have a completely different colour scheme), so this one just HAD to be taken home and reared to adult to finally solve my old puzzle.<br /> Well, what can I say ... I took it, fed it ... and it died on me .. :o((<br /> Rearing Ladybird larvae often isn't as trivial as one might think. Some species are quite picky about the exact food they will thrive on and some species of Aphids can be downright "poisonous" to them, or to some extent their intestine flora can even depend on the continuation of a diet that they were "started on". Whatever the reason, it sucked - big time :-|<br /> The specimen was stored in alcohol of course for future reference, but I was very dismayed that my "mystery larva" would still remain a puzzle.<br /> However, to my total relieve some eggs that were deposited by a female Coccinella miranda hatched about a week later and whad'ya know ... unmistakably the same! :o)<br /> https://www.jungledragon.com/image/77099/coccinella_miranda_w._eggs_and_first_instar_larva.html<br /> This is really quite remarkable in itself, as the first instar larvae of all other species of Coccinella that I know - to me - are totally indistinguishable, while being all black little blobs with very very similar hairs/brushes. But (like I said before) this one is VERY different! Just by the colours of the head (yellow with a black cranium) it is already clearly set off, but even in the tiny first instar some of the white stripes on the body can already be recognized. There is now no doubt whatsoever in my mind that the mystery larva on Flickr, photographed by David Marquina Reyes, and this here larva I found on La Palma are indeed Coccinella miranda(!)<br /> That alone is a stunning conclusion too, as the larva is _so_ totally different from all other Coccinella larvae (at least those known to me)!<br /> Coccinella miranda is often quoted as "a tad different" from other Coccinella spp. and is placed in a small subgenus Coccinella (Spilota), together with the much more wide spread Coccinella undecimpunctata, but even that one has the "usual" appearance of other Coccinella larvae (all blueish-black body with orange brushes at least on ab.seg.1 laterally and dorso-lateral):<br /> https://www.jungledragon.com/image/54277/coccinella_undecimpunctata_-_larva_details.html<br /> To me this may even warrant further investigation into the proper placement of Coccinella miranda, but that will take some time. The larva stored on alcohol will be helpful for that however.<br /> So, here are - to my knowledge - the first properly named images of Coccinella miranda larvae available on the internet :o)<br /> https://www.jungledragon.com/image/77105/coccinella_miranda_-_larva_eating.html<br /> https://www.jungledragon.com/image/77106/coccinella_miranda_-_larva_having_lunch.html<br /> https://www.jungledragon.com/image/77108/coccinella_miranda_-_larva_on_finger.html Coccinella,Coccinella miranda,Coccinellidae,Coccinellinae,Geotagged,La Palma (Canary Islands),Ladybird,Spain,larva

      Ceratomegilla undecimnotata The genus Hippodamia has recently been cut up into various different genera, each with subgenera. Hippodamia undecimnotata is now called Ceratomegilla (Ceratomegilla) undecimnotata.<br /> This series is the result of a batch of larvae kindly sent to me in 2017 from Germany by Burkhard Hinnersmann (thanks!), hence these images were taken at my home in the Netherlands but:<br /> THESE ARE GERMAN SPECIMEN - AT THE TIME, THIS SPECIES DID NOT NATURALLY OCCUR IN THE NETHERLANDS (but it has arrived in the meantime)<br /> <br /> The individual variability in the appearance of the larvae is quite stunning - in most Ladybird species the larvae are quite constant (except for differences between the various larval stages of course):<br /> https://www.jungledragon.com/image/79211/ceratomegilla_undecimnotata_-_variability_in_larvae.html<br /> Just for fun and comparison a side-by-side with the larva of the very common 7-spotted ladybird:<br /> https://www.jungledragon.com/image/79208/ladybird_larvae_coccinella_septempunctata_and_hippodamia_undecimnotata.html<br /> After pupating most pupae were attached to the sides of the boxes, this one I could lift out to take nicer pictures:<br /> https://www.jungledragon.com/image/79210/ceratomegilla_undecimnotata_-_pupa.html<br /> As with most "Hippodamia" (s.l.) the beetles can be quite variable in the development of their spots, with spots being larger, smaller or even missing. There is a spot on the lateral margin that is often quite subtle. When it is barely visible the pattern on the beetle starts to look a lot like the common 7-spot:<br /> https://www.jungledragon.com/image/79205/ceratomegilla_undecimnotata_-_tiny_lateral_spot.html<br /> Here is what it looks like when it's larger:<br /> https://www.jungledragon.com/image/79207/ceratomegilla_undecimnotata_-_large_lateral_spot.html<br /> The head patterns also vary. I have a gut-feeling that this may well be sexual dimorphism (with the black head being the ladies), but I need to get this confirmed still:<br /> https://www.jungledragon.com/image/79206/ceratomegilla_undecimnotata_-_mugshot.html<br /> https://www.jungledragon.com/image/79209/ceratomegilla_undecimnotata_-_portrait.html Ceratomegilla,Ceratomegilla undecimnotata,Coccinellidae,Coccinellinae,Coccinellini,Hippodamia,Hippodamia undecimnotata,Ladybird,nl: Zwervend lieveheersbeestje

    Oh yeah so that one needs the name changed too. That one I posted under my wife's name. All her posts are mine actually but when I would sign in under that Google email it would automatically post her name, even though it was a joint account. I suppose giving her credit for all those would be ok. She's pretty great! Posted 5 years ago

      Yes, I was a tad confused at first, but then I saw that Christine had addressed Laura as Matt, so go figure :o)
      Bad thing that I didn't remember that previous post of yours at all, when I started on the new one above ... to much going on in my head I'm afraid :-/ Cheers, Arp

      P.S. Please DO feel free to upload images of the green ones too :-P       Posted 5 years ago, modified 5 years ago
