Woolly Worms Predict WinterSouthern Weather Folklore
Origin
The belief goes back generations in the Appalachians and the rural South, where farmers looked for natural signs to forecast the seasons. Woolly worms - the fuzzy caterpillars of the Isabella tiger moth - were watched closely in autumn. Some said if the worm’s coat was mostly black, a harsh winter was coming. If it was more reddish-brown, the winter would be easier. Others claimed the number of dark bands showed how many weeks of severe cold to expect.
Though similar sayings appear elsewhere in the U.S., the tradition took particularly strong root in Southern mountain culture, where weather signs were part of everyday life.
Notes
Legacy
The woolly worm superstition continues as a mix of entertainment and tradition. While scientists say the worm’s colors reflect its age and environment, many Southerners still smile and say, "The woolly worms know." It remains one of the most enduring weather signs in Southern and Appalachian folklore.
