Types of Beetles

Scientific name: Coleoptera

Beetles are the flying insects belonging to the order Coleoptera, in which, more than 3,50,000 described species are placed. It means, about one third of the described animal species may be beetles.  Thus, it is considered to be the largest collection of living organisms and believed to be in existence since 270 million years ago.
Beetle family is very diverse and wide. Found in almost every part of the world, they are the most common insects thriving in a varied range of habitats except polar and marine regions. The food habits also differ in each and every species, depending on their habitat. Some feed on plants and leaves, whereas some are carnivorous; they catch insects or invertebrates to eat. There are also other types like beetles feeding on fungus, pollens, crustacean and other insects.

Types of Beetles

The Coleoptera is a very large group of insects, and is the largest order belonging to the class Insecta. It has been classified into 5 suborders namely,

Suborder Adephaga

This suborder is the second largest of the Coleoptera order that hosts around 40,000 known species of beetles categorized into 10 families. The families under this suborder are:

  • Carabidae Latreille
