LEARNING OBJECTIVES OF SECTION
After completing this section students should be able to:
- Describe the basic classification used for insects and other animals.
- Explain how taxonomic keys help in the identification of insect orders.
- List the major orders by technical and common name.
- Describe the wide range of metamorphosis that occurs in the insect orders
- Explain the differences between primitive and modern wings.
Terms: Taxonomy, Class, Order, Genus Species, Linnaeus, binomial nomenclature, Arthropoda, Chelicerae, Pterygota, Apterygota, Paleoptera, Neoptera, Order and common names of major orders.

* * Know Order and Common Names of these groups.
- Describe the differences between the "new" wings of some insects and the "old" wings of others.
- List 10 insect orders and give the common names of each.
- What taxonomic categories make up the scientific name of an insect (or any other organism)?
- Why do some insects have no common names?
- What is a taxonomic key?
