Thousands of monarch butterflies will be released today at the Bruce Peninsula National Park Visitor's Centre in Tobermory.
The Escarpment Biosphere Conservancy is hosting its final of two weekends of the Monarch Butterfly Festival.
Spokesperson Bob Barnett says Tobermory and Cape Hurd are the best places for netting, tagging and releasing the insects because it's a natural habitat for the monarch.
Barnett says the monarch butterfly will migrate to Mexico for the winter --- something that is fascinating because not many insects migrate.
And he says they will travel over four thousand kilometres.
He says the Huron shoreline acts as a natural corridor to get the butterflies to Mexico.
Barnett says the generation they tag Saturday and release will make it to Mexico, and it will be a third generation of that butterfly that migrates back to the Peninsula next spring.
The Monarch Butterfly Festival will also feature a National Film Board feature movie Saturday night at 7 PM.
The public is invited to join the tagging and releasing of the butterflies at the Visitors Centre between 10 AM and 6 PM on Saturday and Sunday
