Charting the Monarch butterfly migration

I'm an avid raiser of butterflies, and will during the year post photos of the monarchs and black swallowtails as they grow and eclose on our screen porch. Too early in the year for anything yet (though we do have BST chrysalids overwintering that will emerge in a few weeks).

In the meantime, the above was an interesting discovery that I found posted at GardenWeb's Butterfly Garden Forum. It's an animated GIF which charts the progress of the monarchs as they migrate northward. If the image above doesn't animate for you, or if the animation has finished by the time you scroll down to this entry, you can access the original at THIS LINK.
