VERMILION, Ohio — Mark your calendar! The official date has been set for the 47th Annual Woollybear Festival.
This year’s Woollybear Festival will be held on Sunday, October 6 in downtown Vermilion.
Each year, tens of thousands of people head to Vermilion to part in the festival that began with a fundraising idea and an insect.
The Woollybear Festival is the largest one-day festival in the country.
People and pets dress up in their brown and orange as a tribute to the forecasting caterpillar. According to legend, the wider the brown stripe on the woollybear, the milder the winter weather.
