Retired CPO, there once was a time when the insects were large and they ruled the world. It was the time before the dinosaurs, about 300-million years ago. The earth had a far richer oxygen atmosphere which was a factor in their large sizes. Dragonflies fossils show that they were about three feet in size.
Yep, well aware of that. Would have loved to see it, from inside a shark cage! No need for a macro lens back in the day!

Your lighting deserves special merit on these also. Excellent++.
Thanks, Fotoartist. Illumination is the most challenging part of macro/micro photography for the subject is within a fraction of an inch from the tip of the lens or objective. The challenge is that this puts the light that close too so glare and specular highlights are a real obstacle to overcome. It's quite a bit different shooting a model several feet away with studio lighting than an ant that nearly touches the tip of the microscope objective with regard to how the illumination will be controlled.
My largest battle is with specimens that have bright colors such as whites and yellows for they are highly reflective and they easily blowout or create haze. I shoot full manual and microscope objectives do not have any aperture control so they shoot wide open. I keep the ISO at the camera base of 200 and I let the white balance follow the subject and lighting. What I do control is the shutter speed by dialing it in while observing the histogram keeping it a tad away from the right (white) for once it goes to the right the highlights and brights are blown. I can open the shadows in post however I cannot restore anything that is blown out.

CPO, thanks for the chuckel. It reminded me of the introduction of the "Flintstones" where the carhop brings out the dinosaur rack of ribs and they are so big and heavy that it flips his human-powered car. Things were much bigger back then.
