Why are insect so numerous?

Answer 1

There has been debate on why insects are so successful in nature mostly it starts with how they are able to adapt so quickly and several evolutionary traits.

For one insects evolved to have an exoskeleton and tendons and muscles are fused directly to this outside skeleton and enables them to move quickly and nimbly, to Dodge predators and catch prey. So more insects are able to survive to mate and reproduce to create another generation of insects.

Another main reason is that insects have a very short reproductive cycle, it takes very little time for another generation of insects to be born and grow into adult hood. Also many insects can reproduce asexually (without the need for male sperm) which can lead to a large amount of insects in a short period of time.
