This is off Whatsthatbug.com. The fellow who took this pic was also in Fl. This wasp is Campsomeris quadrimaculatus.
It probably all the new flowers I put all over the yard but I do have alot of hornets. Well the way people are talking I guess I'll stay farther away from bees, wasp, ect. LOL LOL
It looks some what like a Yellow Jacket.If it is you will know what a stink really is.Just not sure.They do have a yellow stripe tail.
