This is a rose from a large bush on the side of my house, taken with my 50mm 1.4 with a 25mm macro tube (no AF) and my LED lens-mounted light. As you can see that even with an external light in sunlight, the DOF is still very tricky and thus, so is the trick of finding a focus point.
Don't know what kind of butterfly this is. I photographed this during my inaugural test of my 70-300mm with a 7, 14, and 26mm extension tubes on at 15 feet. I wish I was at 5 feet. Not great, but not bad either.
