A portion of the rear wing of a male Flame Skimmer Dragonfly, Libellula saturata, Cox Creek, Albany, Oregon, USA. Dragonfly wings are not flat 2-dimensional structures, but rather, they are 3-dimensional, with grooves and ridges running lengthwise along the wing making it rigid, but allowing it to flex from base to tip and front to back without breaking. The membrane of each cell surrounded by veins creates a network that is very resistant to shearing forces. Tiny spines along the veins have very subtle, but cumulative affect on how air flows across each wing The whole wing acts as nature's most perfect airfoil. AND there are 4 of them, each independently movable and they can also rotate about 180 degrees. Dragonflies and damselflies are the only insects whose wings are controlled and powered by muscles that are attached directly to the bases of each wing. Independent sets of muscles raise, lower and rotate and un-rotate each wing. Focus stacks shot with a Nikon D810 and a Mitutoyo M Plan APO 5X infinity microscope objective.
