Watch is a cooperative network of students, teachers, volunteers, and researchers
dedicated to the study of Monarch butterfly (Danaus plexippus) and its spectacular fall
migration. Monarch Watch welcomes new members.
principle activity of our members is tagging Monarchs during their migration in the fall.
The purpose of this large-scale mark and recapture study is to determine the
pathways Monarchs (east of the Rocky Mountains) use on their way to overwintering areas in
the mountains near Mexico City. In the fall of 1998, 200,000 tags were sent out to
"Monarch Watchers" and we estimate that 80,000 Monarchs were tagged--more than
400 of these butterflies were recovered in Mexico.
