First Monarchs Have Arrived At Wintering Sanctuaries


During the first two weeks of October, south winds prevented migrating Monarchs from making a lot of progress on their flight southward. Cold fronts were weak during this time, and wind blew from the north infrequently. On Oct.12 this persistent weather pattern broke, headwinds subsided and thousands of Monarchs were seen migrating through Texas. By Oct. 20 the first Monarchs entered Mexico and by the 23rd the first butterflies had reached their wintering grounds. Follow their progress as they continue to stream across northern Mexico, headed for their sanctuaries, at

  1. Am I too late to order a calendar? I see that this is the last day to order but it isn’t clear how to alert you before I send my check. I would like to order two calendars. Many thanks, Candace

    I collected some seed pods from a field where there are many–near the wild apple orchard at the Windsor prison lands. Today I will distribute them to another field that used to have milk weed but was overly mown and worked in recent years. Now this field is being left alone again and the trustees who manage it want to mow late, to support the milk weed. I will scratch up the dirt in some likely places on my own land too.

    Nice shot of the Monarch Mary. Correct me if I’m wrong, shot with the 100 mm f/2.8 macro?
    I saw a single monarch this season up here in the highlands of Corinth, VT this summer down at the pond & another one a week or so later up at the house, probably the same one… 🙂

    • Yes, 100mm macro, my favorite! Friends trying to convince me to get a Canon SX60, but so far I’m resisting…
