Color and Appearance:

August 13, 2020: As I was starting dinner on August 5, I looked out the window and saw a monarch pausing to lay an egg on the leaf of our common milkweed. My camera did not get a very clear picture, but it is there. A week later the egg is gone, and there is some evidence of munching on neighboring leaves. I couldn’t find the caterpillar, but he or she may be hiding.
