Common worldwide or nearly worldwide genera are Aeshna and Anax. Anax includes some of the largest dragonflies, including the North American A. walsinghami, Hawaiian A. strenuus, European A. imperator and A. immaculifrons, and African A. tristis, but these are all exceeded by another member of the family, the Asian Tetracanthagyna plagiata, which by wingspan and weight is the world's largest ...
Dragonflies having simple flaps shed the eggs in water, mostly in flight. Dragonflies having ovipositors use them to puncture soft tissues of plants and place the eggs singly in each puncture they make. [32] [34] [35] [36] Dragonfly nymphs vary in form with species, and are loosely classed into claspers, sprawlers, hiders, and burrowers. [17]
The green darner is a large dragonfly; males grow to 76 mm (3.0 in) in length with a wingspan up to 80 mm (3.1 in). [9] [10] Females oviposit in aquatic vegetation, eggs laid beneath the water surface. Nymphs (naiads) are aquatic carnivores, feeding on insects, tadpoles, and small fish.
The insect family Macromiidae contains the dragonfly species known as cruisers or skimmers.They tend to fly over bodies of water (and roads) straight down the middle. They are similar to Aeshnidae in size, but the eyes are green and just barely meet at the top of the head.
Their wings remain clear with amber coloring at the base until the ends of their lives, at which point they become smoky in color. [9] The average mature Hine's emerald measures 2.5 inches (6.4 cm) in length and has a wingspan of 3.5 inches (8.9 cm). [9] On average, female dragonflies are slightly longer than males. [11]

Oppositely, females tend to be less active when near the water and prefer to be in areas with overgrown plants and grasses. Female dragonflies typically only go to the water when they are in search of a mate or if they are laying their eggs. Unlike female dragonflies, males have two different types of flight: search flight and patrol flight. [8]
