Happy Halloween and Dia de Muertos, Monarch Update 2026, and VoTe!

Dear Friends,

In thinking about this past summer of Monarchs, I made this short reel to not only celebrate Dia de Muertos, to not only provide images of wildflowers that support Monarchs throughout their breeding period and migration, but to also encourage everyone to vote. Vote as if the very survival of Monarchs depended upon your vote. Not just Monarchs, but all living creatures. The EPA, National Parks Service, Clean Water Act, Endangered Species Act, NOAA, and states rights to help our environment are just some of the protections under brutal attack.

Monarch Summer 2026

We had a truly beautiful summer for Monarchs here on Cape Ann, with reports from all around the Island of Monarchs in gardens and meadows. Beginning in July, Charlotte and I collected over 50 eggs in our garden and we had at least 50 successful chrysalides. We stopped counting after 50. I think perhaps we were so fortunate because we had many warm, dry days or possibly because Common Milkweed is taking over my front borders. The wind currents also have much to do with whether or not northward migrating Monarchs are shifted toward the east.  Whatever the reason, we were overjoyed to be blessed with so many eggs and cats.

Overnight Monarch Roost

After such a great summer, and because the goldenrod everywhere looked so lush and dazzling, I was hoping for a spectacular migration. The migration turned out to be fairly steady, but nothing like the ones we had in 2006 and 2012. I check for Monarchs everyday, sometimes twice a day, beginning on September 1st. Each day I found a small passel here and a small passel there traveling through. The most in one day was almost two dozen on Eastern Point drinking nectar from the Seaside Goldenrod. We did have one small overnight roost of about 11 or 12 in a Black Cherry tree. Although we on Cape Ann had modest numbers migrating along our shores, Cape May, which is 400 miles south and a major stopover on the Atlantic Coast Monarch’s migratory route, had a banner year.

Monarchs have already begun arriving in Mexico. Many are now outfitted with teeny tiny radio transmitters, called The The BlūMorpho Transmitter, and we are learning so much more about the migration. For example, it has been thought that Monarchs migrate during the day and that Atlantic Coast Monarchs take the safer land route, hugging the coastline. But, as you can see from the maps below, a number of the Monarchs tagged at Cape May have been recorded flying non-stop at night over the Gulf of Mexico.

How to welcome Monarchs to your garden –  Note that in this short reel, in the upper right corner, I’ve labeled all the clips with the name of the wildflower (and one tree species) that the Monarchs are either drinking nectar from, depositing eggs upon, or roosting in. Plant these wildflowers and when it’s a good year for Monarchs, you, too will be blessed with a bevy of butterflies (and not just Monarchs!)

Red-spotted Purple and the Brilliant Blue Iridescence Found in Butterfly Wings

Little flashes of blue iridescence flitting through the garden quickly caught my attention.

A number of black butterflies sport blue iridescence in their wing scales, including the Pipevine Swallowtail, female Eastern Black Swallowtail, Red-spotted Purple, and the Spicebush Swallowtail. Which one was gracing our garden today?

The newly emerged beauty was a Red-spotted Purple, which I had not seen for several years! The much tastier (to birds) Red-spotted Purple Butterflies are thought to have evolved to mimic the foul tasting and toxic Pipevine Swallowtail. Red-spotted Purple caterpillars eat non-toxic leaves of Serviceberry, oaks, Black Cherry, aspens, birches, Eastern Cottonwood, and hawthorns, which would make both the caterpillars and adults appetizing to birds. By mimicking the Pipevine Swallowtail, which eats toxic foliage of plants in the genus Aristolochia, the mimics–Red-spotted Purple, Spicebush Swallowtail, and female Eastern Black Swallowtail–find some protection, to a certain degree.

The beautiful blue iridescence in butterfly wings is created from the microscopic ridges, cross-ribs, and other structural layers of the individual scales, which play with light waves to reflect brilliant blues and speckles.

We had just watered the garden and I think the Red-spotted Purple was drinking up droplets of water. Perhaps there was salt or some necessary nutrients in the droplets when mixed with the foliage.
