I have received a couple of emails recently wondering why their caterpillars were not doing well or dying.
One of the experts,Dr. Karen Oberhauser, in a recent Monarch program says that only 2% of Monarchs make it from the egg to butterfly stage. She mainly talks about insects and parasitoids, but there are also diseases and even the milkweed liquid can kill the small caterpillars.
If you do want to increase the odds of the Monarchs, you can raise them yourself. It’s a fun process and fairly easy to do.
