Dragonflies are a class of ancient insects belonging to the order Odonata. They have a slender body with two pairs of transparent and multi-winged wings that flatten out on either side of the body at rest. The head has a pair of compound eyes, which occupy most of the head, making it have excellent visual ability and can keenly capture moving objects. Incomplete metamorphosis insect. The larvae live in water, breathe through the gills, and prey on small aquatic organisms. The adults, on the other hand, fly through the air, feed on other insects and are excellent fliers, able to move, hover and turn quickly in the air. It is widely distributed around the world, especially in tropical and subtropical regions.

He is one of the strongest members in the insect kingdom in terms of flying ability, known for his agile flying skills and hunting ability. The body size ranges from small to large, and is divided into three parts: head, chest, and abdomen. The head usually has a pair of large and prominent compound eyes, providing excellent visibility. The wings are transparent or semi transparent, with two pairs, the forewings and hindwings, which can quickly adjust the angle during flight, achieving high difficulty movements such as hovering, quick turning, and diving in the air. Larvae live in water and feed on small aquatic animals, while adults prey on other flying insects in the air. The hunting method is very unique, able to chase and capture prey in the air.

It is a primitive and diverse group of insects, with approximately 5000 species worldwide. Belonging to semi metamorphosis, it undergoes three stages throughout its life: egg, juvenile, and adult. Wings have unique mechanical structures, making them excellent flyers in nature. They prefer damp environments and usually fly in ponds or riverbanks, where their larvae develop in the water. Playing an important role in ecosystems, larvae can monitor water pollution, while adults prey on agricultural pests such as small moths. Beautiful in appearance, with ornamental value, and some species of larvae and pupae also have edible value. History can be traced back to 320 million years ago, when it was once a 'giant' in the sky.
