Thanks John for the comment. I have seen this wasp a few times before and am most surprised why the length of the ovipositor must be as long as the rest of the body. The female body length varies between 10 – 16 mm. Ovipositor length varies between 7 – 16 mm.
Great spotting, Arne. I have never seen a wasp quite like this one. Everything about it seems to be exaggerated. Wikipedia comments on the unusual "neck" and when I looked up the English translation of the Norwegian "Krage" in "Krageveps", it seems to mean "collar". So, (assuming I got the correct translation) that would make sense. I really like the Norwegian names, they're often better than the English common names.
