 Fred Urquhart

Frederick Albert Urquhart,  (December 13, 1911 – November 3, 2002) was a Canadian zoologist who studied the migration of monarch butterflies, "Danaus plexippus" L. Together with his wife, Norah Roden Urquhart (June 23, 1918 – March 13, 2009), he identified their migration routes and discovered that the migration spans multiple generations of butterflies.After many years of searching and with the help of Catalina Trail and Ken Brugger, the Urquharts found the location in Mexico where the butterflies spend their winter, far away from their summer residence areas in Canada and the United States.
