Insects are one of the most successful and diverse taxonomic groups on the planet. Their success is attributed to the amazing range and complex behaviors they exhibit. They have mastered the abilities to find food and mate, defend themselves, invade new territories, communicate in various ways and cooperate to build highly organized societies. This course will provide a theoretical and empirical overview of insect behavior. We will cover topics related to insect physiology, genetic and evolution. We will learn how scientists study animal and insect behavior, why do insects behave the way they do, what functions these behaviors might serve, and how behavior is shaped by the evolutionary forces of natural and sexual selection. Among the topics we will discuss are learning, memory and decision making, foraging and defense, reproductive strategies and mating systems, communication, cooperative behavior, and social cognition.
