monarch caterpillars on milkweed
We watched them for a long time, marveling at their ability to eat while suspended upside down and admiring their vivid tiger stripes.
When my kids were younger, we would sometimes put a monarch caterpillar along with a short stick and some milkweed leaves in a mason jar with holes punched in the lid. We would watch the caterpillar form its chrysalis, which looked like a little green jewel case. After about two weeks, the chrysalis would begin to darken and we knew to unscrew the lid–the butterfly was about to emerge.
