I'm glad that somewhere on this Earth, the monarchs have a fighting chance of survival!
It's good that you still have plenty of milkweed over there- that is what is helping the monarch larvea survive.
Some places in the U.S. still have it but unfortunately it is being lost to land development or farmers too quick to cut it down because they consider it a noxious weed.
I've ordered 20 cuttings of milkweed to plant in our back yard-- the type of milkweed I've ordered is native to my area. After it gets established , I want to order some monarch larvea and will hatch them and let them go free.
