This is really depends on the type of caterpillar you have/seen. (whatever)
It can take a few weeks;
but before winter arrives, butterflies have the ability to make the process last for months at a time.
I'm no expert but I raised these caterpillars before and all the caterpillars were in their cocoons for about 12-14 days
For ten days
About 2-3 weeks
caterpillars hide in trees
Fuzzy caterpillars turn into moths.
when theyre ready
yes
no
they kiled each other
No I'm guessing
No they do not because if they did it would change their divelopment (makeing the butterfly deformed)
no
You step on it :D
birds tend to not like fuzzy caterpillars so the cute little tent worms use the fuzz as a defense so they don't get eaten
Spikes on caterpillars are not a sign of cocooning.Rather, they occur only on some caterpillar species.
