Well, people have been posting on this forum off and on for years that they read you should mist your chrysalides. I've NEVER done that, because I live where it's humid and usually rains a lot, and any chrysalis that got misted here would mold, which would be the death of it. I raise my caterpillars on my covered/shaded front porch, not in the house, where air conditioning and heat in the winter would drop the humidity.

So, I'd base misting on your particular conditions. If you live where the humidity is very low, or you raise your cats in the house where the humidity is low, misting might be a good idea. I say MIGHT, because chrysalides are sealed, all the liquid stays inside. Misting on the outside would likely do no good. If a chrysalis has a leak, where it might actually absorb some of the water, that would be pointless anyway, because a leaky chrysalis is a dead chrysalis, makes no butterfly.

Just use your best judgment.

I've been raising caterpillars successfully for many years, with deaths from chrysalides and/or cats VERY rare. I don't know why people recommend this - maybe they live in Arizona, and it seems like a good idea to them.
