Our winter has been, thus far, more mild than last year. Less snow to shovel, and warmer temperatures. Still a photo of warmer times may help take off the chill. The wooly worm is a common focus of folklore regarding winter weather predictions. A nice summary of wooly worm trivia can be found at this University of Illinois Extension webpage.
This particular caterpillar was crawling along a trail in Pioneer's Park near Lincoln last September. It won't be long before spring!
