In the Ozarks, the woolly worm—or woolly bear caterpillar—is more than just a fuzzy critter crawling across your path in the fall. Local folklore says you can predict the coming winter by looking at the bands of color on its back. A wider brown middle band supposedly means a milder winter, while a thicker black band at the ends signals a harsh winter ahead.

Some Ozarkers take it even further: if the worm crosses your path heading north, expect snow early; if it heads south, winter will be late. And, of course, it’s considered good luck if one crosses your path at all—so keep your eyes peeled on crisp autumn walks!
