During this online meeting, Lois Diggs will talk about the how, why and when of Monarch butterfly migration. She will focus on the butterfly itself, the history of Monarch tagging, why people tag the butterflies on their multi-generational journey from as far north as Canada down to Mexico, and how anyone can contribute to the citizen science efforts related to Monarchs.
