The Myth of the Woolly Bear

\tLegend holds that the length of a woolly bear caterpillar’s color bands can be used to forecast how severe the winter weather will be. The myth dates back to colonial American folklore but was popularized by a 1948 study. SciFri finds out if there’s any truth to the lore, and what the caterpillar’s fuzzy bristles are really used for.
