The presentation summarizes information about 6 insect orders: Isoptera, Mantodea, Embiidina, Phasmatodea, Coleoptera, and Lepidoptera. For each order, it describes key features such as mouthparts, life cycle, wings, and antennae. It also provides examples of insects from each order, noting their common names, scientific names, and economic importance, such as roles in pest control, soil enrichment, and pollination. The presentation was delivered by a group of 8 students providing an overview of insect taxonomy and classification.
