Caterpillar to Chrysalis

In science we have been studying the life cycle of butterflies and moths. The little guys in the picture came via standard mail 9 days ago and have already experiences some huge changes.  They are Painted Lady Butterfly caterpillars and overnight the amazing transformation for larva to pupa (caterpillar to chrysalis occured!   Talk about excitement in first grade.  Keeping the kids focused on anything but what's going on in this little cup has been a challenge!  We are learning first hand as we watch the caterpillars transform before our eyes, this afternoon the second of our quintuplet group embarked on the journey to it's next phase.  Fascinating.
