Dragonflies are completely metamorphic insects. Dragonfly nymphs live in the water and are called Com Nguoi (also known as My Gods), when they grow up they live on land. As a result, adult dragonflies are often seen living near lagoons or lakes. However, there are also many species that live away from the water.
Dragonfly eggs are laid into the water surface or on aquatic branches and leaves near ponds, lakes, and wet areas or in water plant tissue, and hatch into pre-larvae that live on the nutrients contained in the eggs. They then go on to transform into nymphs with about 9-14 molts (in most species), and become greedy predators of aquatic organisms, including juveniles. . Respiratory by gills. The nymph continues to morph and molt, often at dusk, and continue to develop into a flying species, however color is yet to form. These insects then turn into fertile adults. Males have an organ located near the back of the chest, inside which contains seminal vesicles; they mate using hooks located on the tail of the male’s abdomen to hold the female behind the head; The female bends her abdomen forward to pick up the male’s sexual organs
