Why the strange pose in these images? Is something interesting going on here?

thought about commenting on that but I didn't see the use because I had no idea what the heck it was doing. This person got three shots of it doing pretty much the same thing, so it either repeated what it was doing several times or stayed in that position for an extended period of time. I'd probably have to see the bug in action...you, know, see the context of this position. I have seen some Anoplius groom its abdomen kinda like this after a nesting sequence, but I can't say for sure that's what this one was doing. It's interesting, I'll give you that. I guess I'll have to do some research:-)

I can add some comments on this insect. There is a six-minute gap between the #73876 and #73877. I noticed that when the wasp flew from one flower to another it would straighten out its abdomen and immediately upon landing would go into the position that is shown. Whenever it was perched on the flower it would maintain the curled position.

I've been looking at spider wasps for a while now and I've never seen this behavior. It is indeed interesting but I have never seen it and I can't think of a reason why this wasp would do this. I can always get back to you, though.
