There was a wetland in my back yard as a kid in Minnesota, where a swamp milkweed[0] grew. Monarch butterflies only lay their eggs on milkweed, and their larvae feed on milkweed, so I've seen plenty of Monarch butterflies and caterpillars. In the late 1980s/early 1990s, I remember the local nature center giving a demonstration on their work to tag and study Monarchs using small stickers on their wings. It hard for me to fathom that Monarch butterflies are likely to be declared at-risk soon. [0] https://en.wikipedia.org/wiki/Asclepias_incarnata https://en.wikipedia.org/wiki/Asclepias_incarnata
