Monarchs Move Northeast with Warm Spell
As sweltering heat covered the eastern U.S. and southeastern Canada over the weekend of June 7th, massive numbers of monarchs moved into Massachusetts, New Hampshire, Vermont, Maine, Ontario and Quebec.

"Nous avons vu notre premier monarque aujourd'hui," came the news from as far north as Quebec City, Quebec, at latitude 47N.

Weather reports said a "Bermuda High" was responsible for the heat. When high pressure parks off the eastern seaboard over the Altantic Ocean as it did that weekend, upper level winds blow warm, moist air from the Gulf of Mexico northward. (See maps.)

"When it warmed up on Saturday, monarchs showed up everywhere and the sightings are all over the place," said Tia Pinney of Massachusetts Audubon.

She took her first monarch of the season to Davis Elementary school in Bedford, MA, and CBS News Boston came too. You can watch the story made by weather reporter Mish Michaels.

Among those who saw their first monarch on Saturday was this writer. Thanks to everybody south of Vermont who gave my monarch the habitat she needed for her journey north!

Keep your eye on the north central region next, where it has been cool and rainy this spring. When will the first reports come from Manitoba and Sasketchewan?

  • Merci, gracias and thank you to Don Davis for forwarding this week's reports in French from the Amateur Entomological Association of Quebec!
