Monarch butterflies go through four stages during one life cycle. The four stages are: the egg, the larvae (caterpillar), the pupa (chrysalis), and the adult butterfly. At Hamilton High School the students have established a habitat for the Monarch butterfly by planting milkweed.
The photo below was taken recently of a caterpillar that has attached itself to a Brussels Sprouts leaf. If all goes well a chrysalis will form and a butterfly will emerge. I’m crossing my fingers that a bird doesn’t get to it first. Nature can be so cruel.
