Mallow butterfly mania

The first mallow plant (a red-flowered butterfly plant that appeared as a mystery last year see here) is hosting 4 chubby, happy monarch caterpillars. They're munching it up and being just generally adorable.  I bought a second mallow plant last weekend, which will have yellow blossoms, and was thrilled to get an adult monarch hanging around all Saturday. It was oddly unafraid of me that  so I was able to take some photos and videos, even got one of it laying eggs on the new plant.
