Nearing Northern Limits
Almost There...
In the central region, the northernmost first sightings of monarchs have reached milkweed's northern limit in southern Manitoba and in several of the Great Lakes Islands, notably Beaver Island and Manitoulin Island.
In the east, monarchs have reached southern Canadian provinces of Ontario, Quebec and Maine in the U.S.
Generation Two
Females are laying eggs of the 2nd generation now. These monarchs will be the grandchildren of butterflies that overwintered in Mexico. In central U.S., monarch caterpillars have been sighted as far north as Minnesota and sounthern Canadian province of Ontario.
Counting Generations
Monarch generations are continuing to cycle. It takes about one month for each to develop. Over the summer, three generations will be produced in the north.
June: grandchildren
July: great-grandchildren
August: great-great-grandchildren—the generation that migrates to Mexico.
