They can travel as far as 100 feet or more and the chrysalis are very hard to find. Yes, wasp and lizards do eat them. They can withstand temps down to 25 degrees if they are not wet. If you continue to raise inside then you will have to keep them if the weather gets bad. I can help you with that. This year scientist think that the population will be low again so every Monarch counts.
