Scientists fear the unusually warm weather we've been having, may interfere with the annual migration of monarch butterflies.
This is the time of year the butterflies start winging their way to Mexico for the winter, but thousands are still basking in the warm Ontario weather.
Clusters of them are still being found in Point Pelee National Park.
Experts now are afraid the butterflies will be stranded far north of where they would normally be this time of year.
