What type of insect is a dragonfly?

Dragonflies are beneficial insects. Young insects can prey on cockroaches or other small animals in the water. Sometimes, insects of the same species also eat each other.

Both adults and larvae are carnivorous, and eat more pests. Adults can prey on mosquitoes, flies, and some can also prey on butterflies, moths, bees and other pests, which are actually beneficial insects.

Dragonflies belong to the class of insects, which is a common name for invertebrates, insects of the class Insecta, Rounded Dragonflies, and Paraptera. The base of the hindwings is slightly larger than the base of the forewings, and the wing veins are slightly different. When resting, the wings lie flat on the sides.

The larvae are short and thick, with rectal gills and no caudal gills. There are 11 departments in total, including 3 general departments, including the general family of dragonflies, the general family of dragonflies, and the general family of dragonflies. Flyflies and dragonflies are the most common and are widely distributed throughout China.

Dragonflies are insects. Dragonfly is a generic name for invertebrates, insects, dragonflies, and suborder Paraptera. The base of the hindwings is slightly larger than the base of the forewings, and the wing veins are slightly different.

When resting, the wings lie flat on the sides. The larvae are short and thick, with rectal gills and no caudal gills. There are 3 general departments, including Aeshnidea, Cordulegastroidea, and Libelluloidea, with a total of 11 families.

Dragonflies

Dragonflies are carnivorous insects. They prey on a variety of agricultural, forestry and pastoral pests such as flies, mosquitoes, leafhoppers, midges and small butterfly moths. Dragonflies are an important class of natural enemies that are beneficial to humans.

"Dragonfly dotting water" is a biological characteristic of dragonflies laying their eggs in water. The larvae (larvae) live in water and live for a period that varies depending on the species, ranging from 2 years to 3 to 5 years.

Research on dragonfly wings focuses on mechanics and biomimicry. Because dragonfly wings have two special structures, wing knots and wing moles, it is an excellent flyer in nature. In terms of mechanical research, it is found that the wings of dragonflies in the air will be affected by horizontal force, vertical force, torque, bending, and action when flying and turning, and it is found that dragonflies fly at slow speed and fly in the aircraft.
