Did you know that you can raise butterflies anywhere? I had no idea this was possible until I was in graduate school. Apparently many libraries do this each summer – how fun! But you can easily do it in your own home, office, classroom – wherever you’d like. Although it’s a great way to teach kids about the life cycle, it’s also a unique way to have some fun this summer. & what a great conversation starter – I mean, how many people do you know are growing butterflies in their living room? Place it somewhere prominent, & have a blast!
Although you can purchase butterfly kits from various companies, all you really need is a large jar & a steady supply of milkweed.
Step One: Prepare the perfect home.
A large, clear jar is just the place to raise your future butterfly. The bigger the better, so if you’ve hung onto that gallon pickle jar, you can put it to good use now! Place a stick or two inside, lengthwise, so the caterpillar (& later the newborn butterfly) has something to crawl on. Cover the jar in screen or cheesecloth (both available in craft stores) & secure with a rubber band. Don’t put the lid on, even if you do pop holes in the top – it won’t provide adequate ventilation, & the caterpillar can cut itself on the sharp edges. Ouch!
Step Two: Secure a source of food.
Milkweed leaves are the life source of the butterfly – eggs are laid on them & caterpillars gnosh on them each day. You’ll need a steady supply of them to feed your caterpillar, so either find a nearby plant or plant one in your yard! You can get free seeds here, although your local garden center may have plants for you to purchase. Personally, I recommend planting some in your yard – you’ll have a steady stream of butterflies each year!
If, however, you’re lucky enough to have a field or forest within walking distance, there’s no need to spend the cash. Milkweed grows everywhere, & there are over 100 varieties in North America! There’s a photo guide here to help you identify the plants.
Step Three: Locate caterpillar eggs.
Monarchs generally lay one egg per milkweed plant, so it’s time to start exploring! Watch for butterflies landing on milkweed; it’s a good sign one has been laid!
Once you locate an egg, carefully remove the entire leaf & place it in your jar. It takes about 3-5 days for the caterpillar larva to emerge. Each day, make sure the leaf hasn’t dried out – if so, place a new leaf in the jar so the little guy will have something to eat when he appears!
Step Four: Don’t forget to feed your new friend!!
Place a few fresh leaves in the jar every day for your caterpillar. It’s extremely important that they’re fresh, as the longer the leaves are away from the plant, the drier they become, & thus less nutritious for your caterpillar. If you must gather some a few days in advance, place in a plastic bag in your refrigeration for no more than two days.
In about two weeks, the caterpillar will begin the transformation into a beautiful butterfly. This site has great pictures to illustrate the steps he’ll take in order to do this!
Step Five: Release the emerged butterfly into the wild!
Once your newborn has emerged from the chrysalis, bid him farewell & release him into the wide world. Celebrate this glorious ocassion with something wondrous, & be sure to take pictures of his first flight!
