My mom used to raise Monarch caterpillars for her elementary school class. I remember that it was always difficult to find milkweed even back then. We had to walk a certain hiking trail to find some and then search the plants for a few caterpillars. I don't ever remember seeing large patches of milkweed, only a few scattered plants with perhaps a dozen or so plants over a roughly one mile hike.
