We looked at Bugguide.org and alot of other photos of sawflies and even though they are a good match in terms of body & wing we couldn't find one that had this one distinct cream colored band on the lower third of its abdomen and the Cerceris fumipennis did so that's why we chose it. So much of the sawfly information out there deals with the larval stage since it is the one that causes damage and concern. I will send an ID request to bugguide.org and see what they come up with
This is a lovely little wasp, but I am pretty sure it is not Cerceris fumipennis. If you compare your image to the ones on the link I have provided, you will see that the wings of your wasp are mostly clear, not the dark smokey coloration of C. fumipennis. The body shape and white markings are different as well. http://bugguide.net/node/view/38173
I think this wasp might be a type of Sawfly. Many species of sawfly are difficult to identify and I am not sure which one this is. You might want to start your search here: http://bugguide.net/node/view/112/bgpage...
