A Natural Wonder Of The World Feb 22, 2009
Each November an estimated 300 million Monarch Butterflies begin to migrate from east of the Rocky Mountains. They head south from Canada and the United States to take refuge in a high coniferous forests, approximately 75 miles northwest of Mexico City in the northeastern portion of Michoacan State, Mexico. This is a journey for approximately 3,000 miles. Day trips from Morellia & San Miguel are possible. The 2 best access points are El Rosario and Chincua. There are unusual vibes at both due to the conflict with loggers. The visit requires walking several miles up to at times 11,000 feet in elevation over rough trails. Horses are for hire if needed at Chincua. As recently as 1975 the purpose and destination of this migration was a mystery. The butterfly viewing season begins in December and runs until April. The peak population is present in January and February.
Once the Monarchs reach these high forest they form colonies, occupying a small geographic area. They are at times so dense on the trees that they make the trees appear to be black and orange. To date seven colonies have been identified in the State of Michoacan. Only two of the colonies are open to the public. The butterflies will spend the winter months resting and recharging to prepare for their trip back north in the spring.
AMAZING MONARCH BUTTERFLY FACTS
1) Some Monarch butterflies migrates over 3,100 kilometers, without previous knowledge about the location for their winter vacation.
2) A male Monarch butterfly is distinguishable from females by the thinner vein black pigmentation and swollen black pouches on the hind wings. The swollen pouches are scent glands.
3) The monarch butterfly has a single food source during its larval stage, milkweed.
4) Milkweed contains a chemical that apparently tastes awful to birds. This taste is transferred to the larvae. I bet birds can eat just one Monarch butterfly!!!
5) A Monarch butterfly caterpillar eats so much and so rapidly that it will sheds its skin four times within two weeks of hatching.
6) A Monarch butterfly caterpillar at two weeks of age can weigh 3,000 times of its weight at birth.
7) Once the Monarch butterfly has emerged from its pupa, fluid must be pumped into the wings and permitted to harden before fight.
8) Some scientist believe that Monarchs use the magnetic field of the earth and/or the position of the sun to find their way to Mexico.
9) Once the female Monarch lays her eggs (about 400) on a milkweed plant she abandons her young.
10) A Monarch butterflies that breed early in the summer die within three to six weeks. If a Monarch butterfly does not breed before late August, its reproductive maturity will be postponed and it can live up to nine months. It is these "late maturing" individuals that migrate from Canada to Mexico.
