I watched the first group of tiny Monarch caterpillars and, to my horror, saw about 6 killed and eaten by wasps, so I bought milk weed in pots and brought the remaining caterpillars in to my porch to protect them. It became a significant project with 9 chrysalis. Unfortunately, three cocoons failed and with another three the Monarchs' were born deformed and we had to euthanize them. But the last three turned into gorgeous large healthy Monarch butterflies. We have another in chrysalis now and six more baby caterpillars eating their way to being butterflies. It's a magical process to watch up close. Here are some photos of the 'nursery' and butterflies.
See the three caterpillars on the left?
