"So, as an example, if it's been a wet and a cool spring, the animals may react to that in a certain way," said Niziol. “When I take a look at it, and I look at natural phenomena that occur, like the woolly bear's coat, the height of the bee's nest above the ground, squirrels gathering nuts, to me, it’s more response to what has already happened weather-wise,” said Tom Niziol, winter weather expert at The Weather Channel.

If the worm has a wider band, there’s a milder winter coming.īut how much of this is based on proven science?

If the band on the worm is narrow, it will be a harsh winter. When using wooly bear caterpillars, better known as wooly worms, to predict the weather, tradition says the width of the brown band on the worm is key, according to KSPR.
