Sponsored by California Academy of Sciences, US National Science Foundation, Congo Basin Institute, IITA-Cameroon, the Ant Course is intended to help both professionals and interested amateurs learn about identification, behavior, and ecology of ants. The website has more details.
It isn’t offered every year and the last time was in 2015 (although it looks like there are plans for 2021 and 2022). You can see previous faculty and students by visiting the Ant Course yearbook.
