This observation is absolutely correct.this is not a macro-- it's a close-up. A macro begins a 1:1. You can also crop to attain 1:1.
With a true macro lens, 1:1 magnification (life-size) is obtained at Minimum Focusing Distance (between sensor to subject). The problem with using a 60-mm macro lens, is that MFD provides a short Working Distance (between lens front element to subject) of 96-mm = 3.8-inches. Most insects are hard to properly illuminate at this close range, and spook easily. Your sensor is about 23-mm wide (less than 1-inch), so a true macro of this katydid would capture only 2/3 of body length.
Any insect less than 23-mm can be photographed as a macro, but with shallow DoF. Any insect can be photographed as a close-up (deeper DoF), then cropped as tight as possible.
