Introduction to the Insects
In terms of number of species described, the Subphylum Hexapoda is the largest in the Phylum Arthropoda. Hexapods (meaning "six legs or feet") include the insects (Class Insecta), which dominate terrestrial environments on earth. The subphylum also includes several groups of wingless arthropods of uncertain placement; namely the orders: Diplura, Collembola, and Protura.
