Ooh, have fun with all those cats! Gosh when I had that many cats they were running me ragged keeping the containers clean and full of fresh milkweed. We have let go 99 beautiful Monarchs so far this year. I have three that emerged today which I will let go tomorrow, that makes 102 so far. Also amazingly enough out of the 102 we had 51 males and 51 females! I still have 10 crysallis and about 12 cats. Still finding eggs here and there but nothing like I did back in the end of May.
I am attaching a pic of one that fell from its crysallis when it emerged. Lucky for her I noticed soon after and had her crawl onto my finger, once her wings were expanded I had her crawl onto some netting to finish the drying process. The pic was taken when I let her go.
