Well, our watch has come to an end, unless we happen to find more caterpillars on our milkweed plants. The first caterpillar built a cocoon and emerged as a butterfly this past Sunday. It was then taken outside and put on a milkweed plant. The day started out nicely, but then a torrential rain hit. While I was able to bring the plant (and butterfly) inside during the storm, without being in the sun the butterfly's wings didn't harden and he was unable to fly.
The second caterpillar started acting like he was going to build a cocoon, but he sadly didn't make it to that point.
While we didn't have the best of luck, I'm so glad we were able to do this. Kieran absolutely loved watching the caterpillars and talking about their progress. We had found a good book on them at the library, and we all learned a lot from reading it. It also enhanced our appreciation as we watched the caterpillars. I can't wait to try this again.
