Hi Dwayne, great to hear that the eggs have done well. Your numbers are tremendous!
I got about 75 eggs from the 3 winged female and mine have almost all pupated in the last couple days. I put 50 of them in the new pop up enclosure when they were 4th instar. I collected wild A. syriaca and put it in pint containers filled with floral foam and water. Kept pumping them with more leaves til they got big and fat too!
They have mostly pupated on the top of the enclosure. I really like the enclosure, it makes it easier to deal with a larger number of caterpillars and can put them out into a little sun on the deck to warm up without worrying about predators. Mona, I don't have to worry too much about them overheating - it is already cooling off here, days about 80, with nights in the 50's. Perfect weather really, but a little cool for Monarchs I think.
