Healthy adult monarchs will fly away, on their own, within maybe an hour of emerging from the chrysalis. They don't fly away immediately, they have to hang from a twig, head up, wings down, while the wings take shape, and dry out. They like to hang out and flex their wings a few times before taking flight, so it is normal for them to be walking around for another 30 minutes or so. Also, they will stay close and not fly away if it is too windy, or raining. If the weather is OK, they should be flying within an hour of eclosing. Two hours would be upper limit. So, I think that your monarch butterflies have some sort of infection that is preventing them from behaving as expected. Sorry about that. If you happen to notice dark patches on the green chrysalis, that is a sign of Ophyryocystis elektroscirrha, a common monarch malady.

Thanks For the info!

They all emerged fine, but I didn't release them immediately because it was raining. They started acting weird after they ate the bananas. Like a wobbly drunk kind of behavior. One of them is walking around now.
