Insects are animals that belong to the type of arthropods. We have studied about 800,000 species distributed in all climates. They live both on land and in fresh or salt water. They are generally small, ranging in size from 0.25 mm in length, as in certain insect pests, up to 30 inches, like some butterflies. Most species have a metamorphosis, a set of morphological transformations, reaching the adult stage. For example, a butterfly spends four stages: egg, larva, pupa and finally the latter turns into a butterfly (adult insect). Many insects feed on living plants but there are those who are scavengers and feed on dead plants and animals. There are also parasites and others that are predators, that is, they hunt other insects for food.
To navigate and perceive things from the outside world, the insects have antennae, which are located in the front of the head.
They have simple eyes and compound eyes. The former are on the top of the head, while the latter are on the side of this and are formed by the meeting of tiny simple eyes that can reach a number of 30,000.
What are the species that live in organized groups?
Ants, termites and many species of bees and wasps live in groups, and each individual has a specific function
