First, this is NOT a macro-photograph; it is a close-up. This caterpillar is most likely about 3-inches long (76-mm). A true macro would capture only 1/3 of caterpillar.
Per Canon website at http://www.usa.canon.com/cusa/consumer/products/cameras/ef_lens_lineup/ef_50mm_f_1_2l_usm#Specifications , your Canon EF 50mm f/1.2 USM lens (per Exif info) has a Closest Focusing Distance of 1.48 ft. = 0.45m. This distance is to far to capture even a good close-up, so it appears that your original image was heavily cropped to arrive at this view. This is why macro lenses are recommended.
Your chosen f/8 aperture is too narrow to carry entire caterpillar, and from attached image #1, you can see that DoF falls in front of caterpillar body.
It is imperative to always have an insects eyes in focus, as the eyes are usually the center of attention. Attached image #2 shows eyes OOF.

Thanks very much Douglass, that is exactly the type of feedback I need.
So, in summary, using a 50mm lens with full set of tubes does not qualify as a macro.
I will use my 100 mm from now on, with and without tubes.
Stacked lenses will also qualify as long as a macro lens is used in the configuration, right?

Is your 100-mm a macro lens? If so, manually set it to MFD, and start shooting.
Any long lens & short lens can be stacked to achieve high mag macro images. A long macro lens in stack will achieve higher magnification.
