Chrysalis

Three of our original five caterpillars are still with us. Two of them are in chrysalis form now and one is almost there.

They went from this:


to this (you can see the thread that it is hanging by):


And finally, to this:


Both of the two that are chrysalides now made their transformation while we were sleeping. I found this time-lapse video of the process that we missed. It is pretty interesting and kind of gross.



Oh, in case you, too, have been led astray by Eric Carle's The Very Hungry Caterpillar, I'll share with you what I have learned about the caterpillar to butterfly transformation. A chrysalis is the name for the pupa of a butterfly. A cocoon is a silk covering of a pupa. Butterfly pupae are not covered by a cocoon, but moth pupae sometimes are. Only the pupa of a butterfly is called a chrysalis.
