Finally found a critter.

Hand-held Nikon D3100 at ISO 200, with Tamron 90-mm macro lens, with JY-670 speedlight (at 1/64 power), 1/200-sec at f/22.
I have found that AF makes a big difference, as camera will only fire when in focus (most of the time, anyway). I was using manual focus before, when a sharp image was more luck than good management.

All three images have the image center in focus. However, the eyes in image #1 are above the DoF. I suspect that you are using a small central focus spot. If not, you should be.
One method to avoid missed focus, is to place central spot on an insect eye, press the shutter release halfway down (which locks focus), then slightly move camera to re-compose image, and press shutter release all the way down, to capture image.

Thanks, Douglass. Yes, I use single dot (spot) focus on everything. As an aside, I sometimes have to recenter the red dot, as it one click to the right. I am obviously inadvertently pressing the RH navigation arrow while I'm fiddling around-no problem, just a self observation.

Consider switching to back button rather than half press focus. I find it a far superior method for locking focus and then recomposing.

Yeah, I am a Canon shooter and did not know. In looking I do see there is an AEL / AFL button. How does that operate?
