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.
caterpillars hide in trees
Fuzzy caterpillars turn into moths.
when theyre ready
no
yes
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.
