humans?8) What is metamorphosis? List the four basic types of metamorphosis, with
an example of an insect group that has each type.9) Why do you think entomologists believe the development of complete metamorphosis was so important?10) Define the terms, Instar and generation.11) What are the basic characteristics of the orders, Collembola, Ephemeroptera, Plecoptera, Dictyoptera, Orthoptera, Hemiptera, Thysanoptera, Coleoptera, Neuroptera, Trichoptera, Lepidoptera, Hymenoptera and Diptera?
