The migrating butterflies were extremely late and unusually reproductive this year. Migrating butterflies do not typically reproduce. Rather, they save their energy for a spring orgy in Mexico that launches the following year’s first generation of butterflies.
As October gave way to the first day of November and the hottest temperatures in history, Monarchs continued their reproductive activities–dropping eggs, hatching caterpillars and forming chrysalises up until Election Day. Scientists, citizen scientists and casual observers all wondered: what the heck is going on?

The monarchs are worrying me. They are still here, yet they have so far to go. Large ones* flutter in the trees across the yard from my writer’s perch. The small new beds of milkweed along the river in the King William area are covered with them,* and caterpillars still are stripping leaves to bulk up for their conversion into flyers. They don’t seem worried at all.
Always have been amazed that some of these fluttering flimsy-seeming creatures fly all the way from Montreal, Canada, to Michoacán, Mexico. The caterpillar in the photo is a lucky one we spied on a friend’s patio in Queretaro last month. When he sprouts wings, he will have a much shorter journey to the monarchs’ winter haven.
But the ones on the river and outside my window need to hurry southward before a freeze heads this way. We’re not sure we can count on Nurse Jane Fuzzy Wuzzy to spring from the pages of Uncle Wiggily to patch frozen wings with marshmallow cream.
In Flight Behavior, author Barbara Kingsolver weaves a tale of climate changes confusing migrating monarchs, causing them to lose their bearings and tragically roost in Appalachia one winter.
Entomologist Dr. Ovid Byron speaking to television journalist, Tina, who says, re: global warming, “Scientists of course are in disagreement about whether this is happening and whether humans have a role.”
He replies: “The Arctic is genuinely collapsing. Scientists used to call these things the canary in the mine. What they say now is, The canary is dead. We are at the top of Niagara Falls, Tina, in a canoe. There is an image for your viewers. We got here by drifting, but we cannot turn around for a lazy paddle back when you finally stop pissing around. We have arrived at the point of an audible roar. Does it strike you as a good time to debate the existence of the falls?”
