I had a wonderful look at what I believe to be a Golden Paper Wasp while on a recent trip to Boyce Thompson Arboretum near Superior, AZ.
Golden Paper Wasp (genus Polistes) is very common in much of Arizona, though I'm not certain of the exact species. As always, comments are welcome with suggestions of the proper species identification.
The above photo was taken with my 300mm f/4L IS lens at F/4.5. I'm always impressed with the ability of my 300mm F/4 to perform in pseudo-macro roles. While at Boyce Thompson, I alternated between my 100mm F/2.8 macro and this lens, and I must say that I prefer the 300mm in most cases as it gives a better working distance. If I couple the 300mm with an extension tube
or two for closer focus, my 100mm is relegated to indoor super macro work.
