Dragonflies are a type of insect belonging to the order Odonata and family Odonata. They undergo complete metamorphosis during their evolution, molting multiple times from the larval stage to the adult stage, and undergo significant changes in morphology. The following is a detailed introduction to the complete metamorphosis process of dragonflies:
Dragonflies lay eggs in the water or on plants near the water. The eggs are usually transparent or white in color and small in size. The size and shape of the eggs vary depending on the species of dragonfly.
After hatching from the eggs, dragonflies survive in the form of larvae. The larvae live in the water and mainly feed on small aquatic insects, worms, etc.
The appearance of dragonfly larvae is a long and narrow body with a large head, three pairs of thorax and respiratory organs at the end of the abdomen.
The larvae go through several molt stages, increasing in body length with each molt until they reach a certain size.
Mature dragonfly larvae will climb onto shore or waterside plants, where they will molt into pupae.
The dragonfly's pupa is protected by a hard shell on the outside. In the pupa stage, the dragonfly remains still, waiting for changes in the body.
After a certain stage, the adult inside the dragonfly pupa is fully developed, breaks open the shell, and crawls out to become a complete dragonfly.
Adult dragonflies have two pairs of wings, a slender body, a large head, well-developed compound eyes, and are good at flying and hunting.
The entire life cycle of a dragonfly includes four stages: egg, larvae, pupa and adult. This complete metamorphosis life cycle ensures that dragonflies have the characteristics and shapes suitable for survival and reproduction at each growth stage.
In general, dragonflies undergo complete metamorphosis, from eggs to adults, through different stages such as larvae and pupae, and gradually complete morphological development and life cycle transformations. This metamorphic life cycle plays a vital role in the survival and reproduction of dragonflies in different habitats.
