Using small aperture in single frame macro

The opposite of the previous post, some subjects are more suited for a highly stopped lens, the "wood" tortoise beetle have a face and body with complex geometric structures and need a lot of depth of field to cover the more important part. Also the kind of detail present in the in focus parts is not much diffraction sensitive, there is not need of highly detailed compound eyes as the ones of him aren't so important in composition as fly eyes for example, and the surface structures have a fair amount of detail even at this aperture setting.

Photo is with Canon MP-E 65mm 2.8 macro photo @ about 3.5 magnification, Canon 7D and yongnuo YN560 manual flash. Aperture of f/11, but at this magnification the effective aperture is near f/50
The blue sky is the result of long exposure time of 1/13s and is possible to observe this movement in the right antenna.

If you compare this image with the one from the previous post the dramatic difference in depth of field is not so noticeable, possibly the choice of aperture is much more subject dependent.
