Caterpillar foods: milkweed
This species has been very common on our land until the last few years. 2012 was a pretty good year – we saw quite a large migration through our prairies. In 2013 we saw almost none. 2014 was much better – we didn’t find any caterpillars, but we saw quite a few migrating butterflies.
During migration we see them on Rough Blazing Star, New England Aster, and especially on Showy Goldenrod in both our planted and remnant prairies.

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