when they feel they are getting older, they usually start changing to the cocoon stage from 10 days up to 3 weeks, they just know
:D was i any help?
Caterpillars make a chrysalis when they are ready to transform, they do this during the fall and winter time, then come out in the spring. ^_^ HOPE DIS HELPS!!!
A chrysalis often looks like a leaf that has been folded around and hung upside down. You can see pictures of a chrysalis online at places like The Butterfly Site.
The name for that is Larva.
Metamorphosis is the process that takes place when a caterpillar forms a chrysalis and after some time, emerges into a butterfly.
A chrysalis is formed when a caterpillar goes through the process of metamorphosis to become a butterfly. The caterpillar spins a silk pad, attaches itself to it, and hangs upside down. It then sheds its skin for the final time and forms the chrysalis casing around itself to undergo transformation into a butterfly.
I know any gradual change over a long period of time is evolution
The time that a lava spends in pupation may be brief, as with the Monarch butterfly who only stay in a chrysalis for 2 weeks. However, some species enter into a dormant state when they start pupation and stay in this stage until the appropriate season. They mostly stay dormant through the winter months or during the dry season in the tropics. The time spend in the chrysalis is different for each species of Butterfly. A butterfly does not spin a cocoon, its pupa is called a chrysalis. A moth, however, spins a protective silk case which is known as a cocoon.
no one know it just is. all the time
when the minium thickness is reached
~Feed it a lot of Milkweed leaves, watch it over time. Once it makes its chrysalis, you don't have to feed it anymore~
it is from December 1 until November 30th.
You need to know your change of position vs. change of time.
