Insects (Class Insecta)

Insects (Class Insecta) belong to the Phylum Arthropoda (also known more commonly as 'arthropods')—a group of animals that also includes spiders, crustaceans, scorpions, and centipedes. Like most arthropods, insects have:

• jointed appendages
• exoskeleton
• segmented body
• compound eyes

Insects are a highly successful group of animals. The Class Insecta accounts for more species of animals than any other class of animals. Their numbers are nothing short of remarkable, both in terms of the numbers of individuals as well as the number of species. In fact, there are so many insects that no one knows quite how to count them all. The best that can be done is to make estimates.
