I had my first (known) visit by a Monarch female today. Unlike past years, this year I've decided to collect the eggs and hatch them indoors. I'm doing this because this year we have an explosion of odorous house ants, both outside and inside the house. Much of my milkweed is blooming and there are zillions of ants collecting the nectar, and I understand that ants do eat Monarch eggs.
From today's laying female, I collected 26 eggs.
