Watch one of our Monarch Caterpillars live in action as it transforms into a chrysalis (pupa). We have raised 64 Monarchs this year. With dozens of Monarch Butterflies already released & migrating south to Mexico, and 15 chrysalises currently waiting to open (they are a chrysalis for 2 weeks before emerging as a butterfly!), this is one of our last monarch caterpillars of the year who has eaten so much milkweed she is all set up for metamorphosis!
