Out of 5 in a container, two chrysalises turned clear, as if they would hatch within a few hours, but just stayed that way, while other chrysalises went from green to clear to hatched. It's been at least three or four days? They don't appear 'degraded' at all. I'm wondering why they're taking so long, should I give up on them, or give them more time, or what? It is starting to get a little cooler here, if that makes any difference, but I still see a few cats and plenty of butterflies outside.
