The Lepidoptera Course will run August 4—14th, 2023. Please reach out to us if you have any questions or concerns.

The course is designed for students, amateur naturalists, conservation biologists, and other biologists who have an interest in learning more about butterfly and moth taxonomy. It will emphasize taxonomy, ecology, and field identification of lepidopterans in Southeastern Arizona. Lectures will include background information on the morphology, biology, and ecology of animals and their importance in pollination biology. Field trips will provide participants with collecting, sampling, and observation techniques; and lab work will provide instruction on specimen identification, preparation, dissection, and labeling.
