Caterpillar Condo

Several readers have written to ask how do I manage to have so many Monarch Butterfly caterpillars and chrysalises. The answer is very simple–because we have planted a wonderful little milkweed patch! We grow both Common Milkweed (Asclepias syriaca) and Marsh Milkweed (Asclepias incarnata) side-by-side. Our milkweed patch is planted near our kitchen. When washing the dishes, I can look out the window and watch all the pollinators and fabulous activity that takes place at the milkweed patch.

Several weeks ago, a Mama Monarch arrived and I watched as she gently floated from leaf to leaf, and bud to bud, ovipositing one golden egg at a time. She went back and forth between the Common and Marsh, depositing eggs on both the tender upper foliage as well as the more sturdy lower leaves. I waited for her to leave, but not too long (because the eggs are quickly eaten by spiders) and collected the sprigs with the eggs. I thought I had scooped up about eight eggs and you can imagine our surprise when 19 caterpillars hatched, all within the same day! Female Monarchs like to deposit eggs around the tiny buds of Marsh Milkweed and many of the eggs were hidden within the buds.

Here’s a video of a Mama depositing eggs on our Marsh Milkweed buds. Charlotte was with me that day and we were dancing to the song “There She Goes” as the butterfly was depositing her eggs and it was too perfect not to include in the video.

Our garden is postage stamp size, but I have managed to fill it with a wide variety of songbird, butterfly, bee, and hummingbird attractants. The great majority of plants are North American native wildflowers and shrubs, and we also include a few nectar-rich, non-native, but not invasive flowering plants. Plant, and they will come 🙂

I am super excited to give my children’s program at the Cape Ann Museum on Saturday morning. The program is free and open to the public. I hope to see you there!
