Every fall, monarch butterflies in eastern North America head south, some of them flying up to 3,000 miles to the mountain oyamel forests of central Mexico. The Forest Service says the monarch is the only butterfly known to make a two-way migration like the birds. Here is the amazing part: the butterflies making that trip have never been to Mexico before. It takes three or four generations to make the trip back north, so not one of them has seen the place they are flying to. Yet they find it, tens of thousands clustering on a single tree. Scientists are still studying how they navigate. The God who guides a butterfly that weighs less than a gram can surely guide you home.
