Kudos on a job well done:)
Hopefully, they'll eclose a few days or hours apart. Did they all molt at the same time?

They should be fine. I had some eclose very close to one another and it was amazing how close to absolutely parallel they hung as they dried. If you are worried, you could take a few out from the center and super glue them to a piece of paper and tape them somewhere less crowded. But, I wouldn't worry. Great work, by the way.

I wouldn't mess c them; they know what they're doing.
Best of luck c your awesome brood.

All I know is that they were all hatched in the same day, but turned into cocoon hours apart. Sadly two fell off for some reason right after turning into chrysalids, either get trampled on by other caterpillars or just didnt hang on to the screen tight enough. I started with 30 eggs, 25 hatched, 5 died while on cat stage, 2 fell off as chrysalids. NOW I have 3 day old, 12 cats, plus........60 eggs, may the lord help me;-) but thanks y to you ladies and gents of this website!! I learned so much in just 3 months:-).
