A beetle is a large group of insects in the order Coleoptera.
Beetle is a generic term for creatures in the order Coleoptera. Coleopteran insects get their name because their forewings are hard sheaths, shaped like carapaces.
Beetles are a fairly large group. There are about 350,000 known species of Coleoptera.
The body surface of the beetle is generally covered with an exoskeleton and has two pairs of wings. The carapace-like forewings play a protective role and cover the body and hind wings; while the hind wings are used for flight, fanning at high speed during flight. (Some beetles are incapable of flight)
Coleopteran insects go through egg → larva → pupa → adult, and are completely metamorphic organisms.
Some beetles are closely related to human life and often appear in human vision in life, especially in rural areas with low urbanization.
