Entomology: The Study of Insects and their Relatives Insects and their terrestrial relatives belong to the phylum called Arthropoda and have inhabited the earth for an extensive time. Paleontologists show that the earliest fossils‚ most primitive forms of arthropods date back to the Devonian Period over 350 million years ago (Henning 1981). By the Age of Dinosaurs‚ 300 million years ago‚ insects were abundant in number and diversity. Like the dinosaurs‚ some pre-historic forms of insects were
