9/16/11 Caterpillar rolled up in a non-grass leaf
The rolled up leaf was kept outside over the winter. I wrapped it in a piece of paper towel and put it in a clay flowerpot, buried in the ground up to the rim, and covered with a clay saucer. I took the pot out of the ground at the end of March 2012, and put the rolled leaf in a jar.
5/23/2012 The butterfly hatched.
5/24/2012 Here’s the rolled up leaf containing the pupa after the butterfly had hatched out
