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
