How do you make butterfly nectar?

While hummingbird nectar is typically a 4-to-1 ratio of water to sugar, butterfly nectar is a bit weaker. Try a 10 percent sugar-water solution (about 1 part sugar to 10 parts water), and add a pinch of multivitamins, if you'd like, from a children's vitamin capsule. Or, use Gatorade with a little sugar added-about 1/2 teaspoon per cup.
