Woollybear Festival in Vermilion
The Woollybear Festival fills downtown Vermilion, Ohio with a single day of caterpillar-themed celebration every autumn. Created in 1973 by longtime Cleveland weathercaster Dick Goddard, the event centers on woolly bear caterpillars, whose banded coats folklore uses to predict winter severity. A parade, costume contests, and the comic Woollybear 500 caterpillar race draw more than 100,000 visitors to this Lake Erie shoreline village.
Its insect/weather folklore identity makes it a classic Ohio weird event.
