Monarch butterfly migration research. Researcher's hand holding a tagged monarch butterfly (Danaus plexippus) used in migration research. Monarch butterflies are found throughout North America,and every autumn millions of monarchs head south to spend the winter in semi-hibernation in the warm southern USA and northern Mexico. This photograph was taken at El Rosario Sanctuary,Anganguao,Mexico. The tag was attached in Toronto,Canada. This monitoring of individual butterflies allows insight into the distances they cover,the speed of their flight,and the numbers which take part in each migration | |
