“Hello! I was emailing you to inquire about the monarch butterfly migration that comes through Gloucester. I recently moved to MA and was told that the butterflies migrate through that area, but have found little evidence as to when this usually occurs. After doing some googling I came across your website discussing the migrating monarchs many times. If you have any information for me as to when I should plan to come up and where to go I would really appreciate it! I love reading your articles and am eager to find out more about the migration pattern! Thank you!”
Hi Becky ~ Thanks for writing and wonderful to know you found us through a Google search! The Monarch Butterfly migration through our region is not an exact science. The “when” of the migration depends on may variables including the success of their breeding during July and August, air temperature, and wind flow. When I look back through my records, I would say, generally speaking, we have the greatest number of Monarchs migrating though Gloucester beginning around the second week of September through October 1st. The butterflies are are found in gardens and wildflower fields and meadows throughout our region. You can often see clusters near the Eastern Point Lighthouse.
Do you have space for a garden? If so, and you would like to attract the migating Monarchs to your garden, plant nectar-rich flowers that are in bloom during their migration. Seaside Goldenrod, New England Aster, and Smooth Aster are just three gorgeous Massachusetts native wildflowers that will attract the Monarchs to your garden.
I hope you’ll stop by the dock and get a GMG sticker when you are visiting!
