Your butterfly will not eat for several hours.  It needs to pump fluid into its crumpled wings and let them dry.  After you set the butterfly free, it will feed in your garden if you provide it nectar flowers.  Sometimes they will drink from hummingbird feeders.  Some butterflies like very ripe fruit as their food, too. Make sure your garden is ready. Don't be dismayed if you end up raising moths instead of butterflies. Moths have markings just like a butterfly; while they will be a lot less colorful, the markings are still likely to be intricate and amazing. Even the varying shades of monotone colors are beautiful to behold in nature. When its wings are dry, you can put your finger under its legs and it should hop on your finger.  Walk outside and set it on a flower for some great photos.   If you have done your research, you may know the lifespan of your butterfly – some live as short as a day, so be mindful of this when giving it its freedom. Butterflies need to be free to truly thrive. It's only possible to contain them if you have a large garden they can stay in. What's more, many species migrate – they can only stay with you so long if you want them to live. Some butterflies will live for a matter of days, some will stay a matter of days and then migrate, and others will stay for weeks. Either way, be glad you raised your butterfly successfully and watch for future generations. If you wound up with the Luna Moth, Cecropia Moth, or Polyphemus Moth, don't worry about feeding them. These curious creatures don't have digestive systems.
