Monarchs in Michigan
Fall is here, and with the cooler temperatures and lessening daylight, many different species have begun to migrate. Mammals, birds and even insects make a journey away from their summer range to find a place suitable to spend the winter. One remarkable insect that makes such a journey is the monarch butterfly.
Monarchs from Michigan typically travel south to Mexico to overwinter. Four new generations of monarchs are born each year, so the generation that migrates north in the spring is not made up of the same individuals that migrate south!
Because of this tremendous journey, monarchs have need for a variety of habitats. In the early summer these butterflies lay their eggs on milkweed because that is the only plant their caterpillars will eat. Monarchs also need habitat to overwinter in, not to mention habitat where they can stop and refuel along the way. They are very active insects and require a wide variety of flowering plants to provide the food they need to survive and make their long journey.
Unfortunately, this remarkable insect has had a 90-percent decrease in its eastern population over the last 20 years. Read more
