Thank you very much for your assessment of my publications @agmoore.

I was wondering as I read if human engineers study insects like this to learn from nature's successful engineering.

That same question I asked myself when I was in college, I even remember that I looked for some answer with one of my entomology professors, he told me yes, but he did not know how to give an easy answer because it was something that has bases in different areas of science. In addition, while studying I realized that many of the things that humans have achieved is because they have sought to mimic the behavior or certain biological mechanisms of other life forms, this is part of what is known as biomimicry. I once read that the first design of the "bullet train" in Japan emitted a loud sound when leaving the tunnels, one of the engineers proposed to give the front of the train the shape of a bird's beak, as this piece helps the aerodynamics of the flight of these animals and the sound generated by the train was caused by air pressure, then the modification was made to the train and the sound disappeared, they also noticed that the performance of the train had improved to perfection.

Even if we look at the early designs of aircraft used in the first or second world war, they are very similar to the morphology of dragonflies. However, I only know that the flight of dragonflies has served to give dynamism to helicopters, since this insect is one of those that can stop in the air and move in any direction while hovering, current helicopters can do it, but they cannot back up in the air as these insects do. Engineering is always looking for ways to replicate things that nature has that allow us to improve technological performance or improve our lives, but it is clearly not something simple.
