We live in a world of insects. That makes insects the most abundant group of creatures on earth. They are found all around the world.
Insects are part of a large group of animals called invertebrates.
All insects have 6 legs. Spiders aren't insects, they're arthropods. You can tell they aren't insects because they have 8 legs. The head includes the eyes, antennae, and mouth. The thorax, which separates the head from the abdomen, is where the insects wings and legs are attached.
