When you see a patch of Pussy Willows look, too for the Mourning Cloak Butterfly. Pussy Willows are the caterpillar host plant for Mourning Cloaks. One of the first butterfly on the wing in early spring, Mourning Cloaks winter over as adults in the cracks and crevises of tree bark.
IT’S NOT JUST MEXICO’S FORESTS THAT NEED PROTECTING FOR BUTTERFLY MIGRATION
THEIR ROUTE FROM CANADA IS THREATENED BY OVERUSE OF HERBICIDES AND CLIMATE CHANGE, AMONG OTHER FACTORS
Víctor Sánchez-Cordero, a researcher at the National Autonomous University’s Institute of Biology and Mexico’s lead representative on a tri-national scientific committee that studies the monarch, said that the butterflies’ route from southeastern Canada to the fir tree forests of Michoacán and México state is under threat.
He blames the excessive use of herbicides, changes in the way land is used, climate change and a reduction in the availability of nectar and pollen.
“The commitment to conserve this migratory phenomenon not only focuses on Mexico; it’s a shared responsibility between our country, Canada and the United States,” Sánchez-Cordero said.
The researcher, who along with his team developed a system to monitor the migration of the monarch, said that there is a misconception that the most important – almost exclusive – factor in ensuring the continuation of the phenomenon is the conservation of forests in the Monarch Butterfly Biosphere Reserve (RBMM), located about 100 kilometers northwest of Mexico City.
That idea “has placed great international pressure on Mexico,” Sánchez-Cordero said before adding that he and his team published an article in the journal Frontiers in Environmental Science that shows that the decline in the number of monarch butterflies migrating to Mexico is not due to deforestation in the RBMM.
Deforestation has been drastically reduced in the past 10 years but butterfly numbers have continued to decline, he said.
“The dramatic reduction in the density of monarch butterflies that arrive at overwintering sites in Mexico doesn’t correlate with the loss of forest coverage, which shows that this factor is not responsible for the population reduction. … Other hypotheses to explain the decrease must be sought,” Sánchez-Cordero said.
One possible cause for the decline, he explained, is that the excessive use of herbicides is killing milkweed, a plant that is a main food source for monarch butterflies and on which females lay their eggs. Less nectar and pollen in the United States and Canada as a result of deforestation is another possible cause, Sánchez-Cordero said.
He added that large numbers of migrating butterflies have perished in Texas and the northeast of Mexico due to drought linked to climate change.
To conserve the migratory phenomenon of the monarch – butterflies fly some 4,500 kilometers to reach Mexican forests from Canada over the course of three to four generations – a network of conservation areas along their migration routes needs to be developed, Sánchez-Cordero said. He also said that the routes followed by the butterflies should be declared protected areas.
“A new conservation paradigm is needed. … It’s something that we [Mexico, the United States and Canada] should build together,” the researcher said.
In March I had the tremendous joy of interviewing Ellen Sharp and Joel Moreno Rojas, founders of the nonprofit organization “The Butterflies and Their People Project.” We filmed the interview from the rooftop of their hotel, JM Butterfly B&B, which is located at the base of Cerro Pelon Monarch Butterfly Reserve in Macheros, Mexico. Cerro Pelon is the old volcanic mountain where the Monarchs wintering home was first located by Mexican citizen scientist Catalina Aguado Trail, on January 2, 1975. Trail was at the time working under the direction of zoologist Doctor Fred Urquhart of the University of Toronto.
Joel and Ellen are simply an amazing dynamic duo. They have built a beautiful and welcoming bed and breakfast at Cerro Pelon, the most pristine and least trafficked of Monarch sanctuaries. Largely through the conservation efforts of The Butterflies and Their People Project they have helped provide economic opportunities that have in turn dramatically reduced illegal logging and deforestation of the core protected areas of the forest.
The mission of The Butterflies and Their People Project is to “preserve the butterfly sanctuary by creating jobs for local people in forest and monarch butterfly conservation. The Butterflies & Their People Project is an Asociación Civil (non-profit organization) registered and located in the village of Macheros in the State of Mexico.”
I hope you’ll watch and will be equally as enamored of Joel and Ellen as were we. You’ll learn more about how The Butterflies and Their People Project came to be, the importance of protecting the existing Monarch Butterfly forest sanctuaries, and how jobs and economic growth go hand and hand with protecting the vitally important temperate forests of the Monarch Butterfly Biosphere Reserve. And a bit about how this extraordinary couple met and began their journey in Monarch conservation.

Thank you so much dear butterfly friends for sharing Beauty on the Wing trailer. As I am writing this post, the new trailer just hit 600 views. That is quite wonderful as it has only been three days since we first shared the trailer and because unlike YouTube where if you watch only a few moments of a video it counts as a hit, with Vimeo, you have to watch it all the way through to be counted. By sharing the trailer and generating many views, you are truly helping when festival judges are viewing submissions.
So thank you, thank you, thank you for sharing!!!
Monarchs, Painted Ladies, American Ladies, and Yellow Sulphurs are still migrating through Cape Ann–Massachusetts, New England, the mid-Atlantic states, and all along the East Coast for that matter. There isn’t much in the way of nectar plants available at this time of year. If you have anything at all blooming in your garden, even a Dandelion, it will help butterflies and bees on the wing.
This newly emerged Painted Lady was scrounging around at all the dandelions in and around Eastern Point. You can see why if the deadly herbicide Roundup had been applied to this lawn, there would be nothing for the butterflies.
The above Monarch butterfly was drinking nectar from what appeared to be a dried out stalk of Seaside Goldenrod. Although it may seem of no use to you and I, the Monarch was probing deeply into the florets and finding sustenance.
If you have to tidy up your garden, wait until after Thanksgiving, and go cautiously. Bees burrow into dried flower stalks, songbirds find nutrition in the seed heads, and the caterpillars of many species of butterflies, such as those of the Great Spangled Fritillary, winter over in leaf litter at the base of plants.It is not beneficial to pollinators to invite them to your garden, and then decimate the over wintering species with zealous tidying-up. Take a break, be lazy for the sake of the pollinators 🙂
Another banner weekend for butterflies on Cape Ann with Yellow Sulphurs, Painted Ladies, and American Ladies joining the streams of Monarchs migrating along our shores.
Butterflies struggle at this time of year to find sources of nectar. Whatever you do, please do not cut back your garden until mid-November or so. Best NOT to cut back at all and to leave the drying seed heads for the songbirds and leaf litter and plant stalks for hibernating bees and caterpillars, but if one really must cut back, wait as long as possible.
If you click on the photos in the gallery, each picture is labeled with the name of the butterfly and the names of the late-blooming plants on which they are drinking nectar and building their fat reserves for the journey ahead . Butterflies will even fight over a Dandelion to try to get nectar when nothing much else is available (the best reason of all not to use Roundup on the Dandelions in a lawn).
You may have seen on social media sites the map of butterflies moving through Oklahoma. This is the original story in which the maps appeared: A front full of butterflies swept through Oklahoma City on Saturday
The line on the map above isn’t rain, but from butterflies and dragonflies. We can surmise based on what has been happening along our shores that the species you see in this front are most likely a swirl of Monarchs, Painted Ladies, and Green Darner Dragonflies. The north easterly winds are carrying the insects south.
Below is a map showing autumn and spring migrations. The orange arrow is the fall migratory route of the Monarchs.Anything red represents rain. Blue indicates more unusual shapes, often biological in origin. Notice behind the “butterfly front” the large spattering of blue. That’s where the insects were. (GR2 Analyst)
