Dragonflies were the first insects to fly on Earth and have not changed much since. Some lay eggs in plant material (endophytic) and some directly in the water (exophytic).
Photo one: The Emperor dragonfly is endophytic. (A male Emperor dragonfly is blue all-over and can be seen
here).
Photo two: The dragonflies in this photo are exophytic. The eggs are laid directly in the water while flying, either with the male helping by clutching to her head as shown or hovering close-by to keep other males away). The photo is unfortunately overexposed and fixed as good as I could.
Macros? No, supertele: Sigma 135-400mm (on Olympus equivalent to 270-800mm tele in terms of 35mm film) at 400mm, handheld, ISO 400.
