They’re beginning to cross the road in front of my car as I drive to work in the morning – everyday I see more of them. It has gotten me thinking about these beloved fuzzy caterpillars that children of ALL ages find irresistible. You have to admit – they really are pretty cute!
Most of us have heard the story about how woolly bears can predict the severity of the coming winter by the pattern of the orange and black stripes on their fuzzy bodies . . . but is there any truth in the tale? And how does the story go – does a wide orange band mean a harder winter or is it a narrow orange band and lots of black that predicts the hard winter? I, for one, can never remember!
Well here’s the scoop straight from the Old Farmer’s Almanac:
The longer the middle orange band on the woolly bear, the milder and shorter the winter will be. Conversely, the shorter the orange band, hence the more black on the woolly bear, the longer and harsher the winter will be.
Well, I mean not really. The lengths of the orange and black bands are really a function of the age of the caterpillar. Woolly bears are the larval stage of the Isabella Tiger Moth, a not-very-impressive moth that you might see fluttering around your porch lights at night during the summer. The woolly bear caterpillars molt (shed their skin) several times as they grow and each time they do, the orange band gets longer and the black ends get shorter. So if you see a woolly bear that is mostly orange, that just means it’s older and more mature!
But here’s some food for thought … what if you have a long, mild fall? The woolly bears will stay active longer and keep growing and molting. The orange band will become wider and wider! Hmmmm, does a mild fall predict a mild winter? And what if winter comes early? A shorter fall season will mean that the woolly bears are younger/haven’t molted as often before they seek shelter for the winter, resulting in a relatively narrow orange band and more black on their fuzzy bodies. Is a harsh winter on the way?
The woolly bears I found around the nursery last year were an epic failure as far as predicting our winter – most had a lot of orange and very little black! A mild winter? Not by a long shot! We had one of the hardest, snowiest winters on record in the Shenandoah Valley!
I wonder if they’ll do any better this year.
I haven’t seen any close enough yet to see their color pattern – have you?
