Butterflies Make Chrysalises – Moths Make Cocoons
On the left is a chrysalis of a Black Swallowtail Butterfly. The caterpillar attached itself to the branch, then shed its final exoskeleton revealing the chrysalis.
On the right is a cocoon of a Bagworm Moth. The Bagworm Moth caterpillar formed the cocoon of silk around itself and attached nearby leaves and sticks to the outside for protection.
