Insects are a diverse group of small, invertebrate animals that are found all over the world. They are characterized by their segmented bodies, three pairs of legs, and wings (in most species).

There are over 1 million known species of insects, and they are found in a wide range of habitats, including forests, grasslands, deserts, and even in urban areas.

Insects play important roles in the ecosystem as pollinators, decomposers, and as a food source for other animals. They also have a variety of adaptations that help them to survive in their environments.

For example, some insects have hard exoskeletons that provide protection from predators and the elements, while others have wings that allow them to fly and escape danger.

Insects can be divided into several different orders, including beetles, butterflies and moths, ants and bees, and grasshoppers and crickets.

Some insects, such as bees and butterflies, are important pollinators, while others, such as ants and beetles, are known for their ability to work together in large groups. Insects are also popular as pets and are often kept in terrariums or insectaries.
