This is really dependant on the type of caterpillar you have. :)
It can take a few weeks, but before winter arrives, butterflies have the ability to make the process last for mos. at a time.
Caterpillars spin the cocoons themselves, then moths emerge in a few weeks.
5-6 weeks
about ten days
about ten days

it takes about 10 to 14 days for a mourning cloak butterfly to get out of cocoon.
Probably about ten days.
it takes about 7 to 14 days, depending on the air temperature
The Caterpillar eats until it is fully ready to break out of the cocoon, This may take a few weeks to a year or so. Hope This Helps
The length of the cocoon stages depends on the type of caterpillar. For Monarch butterflies it is 10 days long.
it takes about 4 weeks for it to grow and cocoon and about six weeks 4 it to be a butterfly.
They emerge from their cocoons about ten days after spinning them.
