Thousands of monarch butterflies hang from a tree brach at the Monarch Butterfly Biosphere Reserve in Cerro Prieto, Mexico.





If you’d rather see butterflies on a mountaintop than slather yourself with sunblock on a tourist-packed beach in Cancun, Mexico is an ideal winter destination.





Ecotourism is drawing fans in the central states of Michoacan and Mexico, thanks to the spectacular yearly migration of millions of orange-and-black-winged monarch butterflies.





In delicate swarms, the butterflies head south from the U.S. and Canada to Mexico, where they drip from pine trees and coat mountainsides from November to late March.





“I have on many occasions seen Spaniards, Italians, Americans, Canadians, Mexicans come into the butterfly colonies and literally weep,” said Lincoln Brower, a monarch expert at the University of Florida and Sweet Briar College in Sweet Briar, Va.





“It’s such an overwhelming emotional experience to realize that you’re actually looking at these tens of millions of monarch butterflies that have come into this tiny, little area of Mexico.”





The Biosphere Reserve, a federally protected area nominated for World Heritage Site status, spans more than 50,000 hectares across two states and costs less than $5 US to enter and $10 US more for a guided tour. In some parts, visitors can trek about on rented horses and burros.





Communal farmers own the land and have the exclusive right to conduct tours. For that reason, many guides don’t speak English — so bring a Spanish dictionary if you want to ask questions about the butterflies.





Mexican President Felipe Calderon plans to pump an extra $4.6 million into the reserve’s $36.4-million budget this year, to improve infrastructure and make the area more tourist-friendly.





Four butterfly sanctuaries are open to the public on the property: El Rosario and Sierra Chincua in Michoacan, and El Capulin and La Mesa in Mexico state.





Brower, who has studied the flying insects for 52 years, recommends the Michoacan sanctuaries, which he says are among the most popular and offer amenities such as food, souvenirs and easy access by car. He suggests visitors go in February and March, when the butterflies perform an elaborate mating ritual.





“The males chase the females — they zoom around after them and catch them in the air and drop like a dead weight,” Brower said. “Then the male flies off, carrying the female, and he’ll land up in the trees and mate for several hours.”

  • The butterflies gather in such numbers that cars passing the Monarch Butterfly Biosphere Reserve sometimes have to slow to speeds of only a few kilometres an hour to avoid splattering the delicate creatures on their windshield.
