Query why insects are so successful on land and why there are so many different species of insects. Be sure to provide specific examples to illustrate your rationale.
It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments. In addition, insects can produce large numbers of offspring relatively quickly.
There are so many different species of insects because Insects Have Been Here Longer. Scientists show that many insect groups like beetles and butterflies have fantastic numbers of species because these groups are so old. In contrast, less diverse groups, like mammals and birds, are evolutionarily younger. 'Insects' are the most diverse class of animals. The phylum that insects are in, arthropods, is really much more diverse than the insects. Arthropods are the most diverse phylum of animals because they molt. Insects are the most diverse class of arthropods because they fly.
