MEXICAN MONARCH
A Monarch butterfly rests on a leaf in the Pedro Herrada butterfly sanctuary on
a mountain in the Mexican state of Michoacan on Feb. 1. Monarch butterfly
colonies in Mexico more than doubled in size this winter after bad storms
devastated their numbers a year ago, conservationists said on Monday, although
the migrating insect remains under threat. Millions of butterflies make a
3,200km journey each year from Canada to winter in central Mexicoˇ¦s warmer
weather, but the size of that migration can vary wildly.Feb 16, 2011
