Insect Biology

Course Description

Course information provided by the 2026-2027 Catalog.

Introduces the science of entomology, focusing on the systematics, anatomy, physiology, basic and applied ecology, and natural history of insects. Early fall laboratories include field trips to collect and study insects in the natural environment. A personal collection emphasizing ecological, behavioral, and taxonomic categories is a requirement of the laboratory.

Prerequisites one semester of college biology or permission of instructor.

Fees Materials, $75. Required Lab Materials.

Last 4 Terms Offered 2025FA, 2024FA, 2023FA, 2022FA

Learning Outcomes

• Categorize insects based on basic ecological, behavioral, morphological, physiological, or developmental attributes.
• Demonstrate phylogenetic "tree thinking."
• Name various structures in some insects and compare them with homologous structures in other insects.
• Present an insect collection of appropriately preserved specimens using a variety of collecting techniques -Evaluate morphological characters and use a dichotomous key.
• Conduct an ecological sampling field exercise and write a team report and identify insects in lab using both personal and class-based specimens.
• Sketch anatomical features in personal dissection and lab demonstrations.
