MEXICO CITY: 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 2,000-mile journey each year from Canada to winter in central Mexico’s warmer weather but the size of that migration can vary wildly.
