To raise butterflies, you need to do a couple of things.
1) Determine what species of butterflies are common in your area and find out what larval host plants they each use. That means, what do their caterpillars eat. It's different for different species.
2) Find a local plant dealer that will guarantee that no pesticides of any sort have been used. If you have a Natural science museum with a butterfly exhibit, you might check with them to see if they sell larval host plants. Get those plants and get them going. You'll need a lot of leaves, so when the seeds come out, plant them so that you are constantly enlarging the number of plants you have. Some plants can be rooted. With my milkweed, which I feed Monarchs and Queens with, I cut the stem, let them eat what they want, then put the leftover stem in the dirt. Sometimes a new plant emerges and it didn't require a lot of time on my part or spending more money.
3) Determine how much time you want to spend. If you don't want to spend a lot of time, just planting some good flowering plants (nectar plants) like lantana, duranta, etc. and larval host plants for certain species will bring them. We bring them in as egg or caterpillar. Preferably egg, as they are so many predators that can eat the egg or eat the baby caterpillars. I've heard only 2% of all eggs layed actually make it to adult butterfly. The eggs can also be parasitized and then the caterpillars die at some point during the process, or they make it to chrysalis, but die inside.
If you decide you want to raise from egg, it does take quite a bit of time. I house them in butterfly castles I purchase from
www.livemonarch.com They are wonderful and easy to clean.
