Now, we have tried this before, but without success. Not with Monarchs though. We have a Milkweed plant out back, it is a huge plant, but it does not attract Monarch caterpillars. Some kind of moth lies its eggs on it over the summer. We have never seen it make its cocoon though. At the end of May, of last year, we visited the Greathouse Butterfly Farm, on a field trip. They gave each of the kids a Milkweed plant, and they assured me it was the kind that would attract Monarchs. So we planted them, and while not huge, they have grown nicely.
So, that brings us to the past few days. I really did not expect to find caterpillars this time of year, but am glad we noticed them. I don't think they would have survived the cold, but I could be wrong. We have noticed lots of tiny orange eggs, on the plant, but they must not be eggs, because they never hatch. I am not sure what they are, but they are on both plants.
So, in a couple of weeks, I will be sharing our newly born butterflies. We did have one of those expensive fancy butterfly houses, and nothing ever grew in there. I think it was too cold. These babies are in a large plastic container with a lid. It stays nice and warm in there.
This is how we like to learn about Science. Note, in the picture only one caterpillar has made a Chrysalis, the other one did it over night into the next day.
