Many of us have heard of the story that a small, fuzzy caterpillar Called the Woolly Bear (aka woolly worm or hedgehog caterpillar) carried the prediction of the coming winter on its back. Whatever name you choose to call them, these cuddly looking caterpillars are often found in the autumn after they have left their food plants, a variety of grasses and weeds, in search of a sheltered spot where they can hibernate as larvae for the winter.
According to folklore, the amount of black on the woolly bear in autumn varies proportionately with the severity of the coming winter in the geographical area where the caterpillar is found. The longer the woolly bear’s black bands, the longer, colder, snowier, and more severe the winter will be. Similarly, the wider the middle brown band is associated with a milder upcoming winter. The position of the longest dark bands supposedly indicates which part of winter will be coldest or hardest. If the head end of the caterpillar is dark, the beginning of winter will be severe. If the tail end is dark, the end of winter will be cold. In addition, the woolly bear caterpillar has 13 segments to its body, which traditional forecasters say correspond to the 13 weeks of winter.
