Caterpillar foods: milkweeds
The first Monarchs usually arrive here by the end of June, and the last of the migrating ones are gone by the end of September.
Since 2017 we’ve been doing a ‘migration count’. We count all the adult Monarchs we see on our afternoon walks from the middle of August until the migration is over. Since we take the same walk every afternoon, at about the same time, the numbers give us some idea of how the year has gone for the Monarchs, and the timing of the peak of the migration. Here’s the chart we’ve made of those counts.
During migration they nectar on Rough Blazing Star, New England Aster, native thistles, and Stiff and Showy Goldenrod.

11/2/2014 This is the latest I’ve ever seen a Monarch. I think the odd coloration must be damage from the cold.
