  1. What an interesting case with an unusual shape! Posted 2 years ago
    1. More strangely still - these are a wild construction of mixed home made parts and particles all sorts and still somehow the overall appearance is "typical" for one species or the other, like the clearly different other one I posted earlier:

      1. The shape is so fascinating and makes me wonder why they make their cases that way. What is the benefit and what are they "thinking"...Or, at least what is their DNA "thinking". Anyway, very cool post <3. Posted 2 years ago
        1. Haven't got the faintest, except maybe that the cases look somewhat like bird-poo and hence probably not very appetizing to many predators? Posted 2 years ago
          1. Oh, eww. Good point, I hadn't considered that. Posted 2 years ago
  2. Arp, no rush, but when you have a moment, would love to hear your thoughts on whether this is the same species:

    Coleophora sp., Loonse en Drunense Duinen, Netherlands Casebearer larvae in its pistol-like structure which perhaps mimics dung. Found on oak leaf. It looks very similar to the species posted by Arp earlier:<br />

    1. Hi Ferdy, there are a few species with roughly similar looking "pistol cases", but from what I could find the white membrane in the "trigger area", combined with the host Oak, seems to be enough for the ID. Then again I'm no expert for these ... I suggest you just "identify" it as such and I'll check with an expert next time I talk to one and if they tell me it's questionable I'll get back to you on this, but I'm assuming it should be okay for now.

        1. Update: Ingrid Altmann from Bavaria, Germany saw this post and sent me a link to a nice (although somewhat older) PDF that contains more info on the various cases and hosts of Coleophora spp. :

          Patzak, Helmut (1974) Beiträge zur Insektenfauna der DDR: Lepidoptera — Coleophoridae. - Beitr. Ent., Berlin, vol.24(5/8), pp.158-278.

          From this it would seem that:
          1) The case of Coleophora nemorum is almost equal. This is not a problem as today C. nemorum is seen as a synonym of C. ibipennella :o)
          2) The cases of Coleophora anatipennella look quite similar (figs.39 & 40, pg.179) and in theory this species may rarely also occur on Oak. Comparing the cases of anatipennella and ibipennella on lepiforum.de leads me to conclude that our cases look much more like ibipennella and as this species is also predominant on oak I'd say it would be very unlikely to have these confused with anatipennella:
          So, I'd stick to the ID as is, but it may be nice to have this info with it ...
          Cheers, Arp
