What am I doing this summer? Good question. I'm teaching Integrative Biology 496: Introduction to Beekeeping. If you are a University of Illinois student and would like to learn about the biology of Apis mellifera and how to manage a small apiary for honey or just for fun, please consider this 8-week class.Â Enrollment is capped at 22 in order to maintain a reasonable student to hive ratio.
