A young girl on last month's butterfly walk was very interested in Monarch Butterflies. We turned over a bunch of milkweed leaves looking for eggs and found these newly emerged caterpillars instead. As most of us know by now, Monarchs must lay their eggs on plants in the Milkweed family. Philadelphia Parks and Recreation is contributing to increasing their population by planting Common Milkweed and Butterfly W**d in the meadow. If you plant milkweed species in your yard, you too, may experience the brilliant orange and black of Monarchs visiting you. And maybe they will lay eggs!
