Instructions
Research what types of butterflies live in your area, and what time they come out of their cocoons. In most parts of the United States this is in the early springtime.
Go to a habitat that is inviting to butterflies and caterpillars. Gardens or areas with a lot of flowers and lush foliage is a good place to start. You can also check in healthy forested areas.
Look for butterfly cocoons dangling from the branches and stems of plants. Butterfly cocoons are more delicate than moth cocoons and will therefore be hidden more carefully in the shade or in deep foliage.
Look at the cocoon and identify if the outside of the cocoon is hard or covered in silky thread. If the cocoon looks soft, it is a moth cocoon. If the cocoon is hard and green, it is a butterfly cocoon.
