What do you feed a monarch butterfly?
Nectar. Canned fruit nectar offers everything the newborn butterfly needs to develop further. Use the canned nectar in place of sugar water and either place it in a plastic bottle cap or saturate a tissue with it. Or provide nectar-bearing flowers, especially milkweed -- the monarch's food of choice.
Do butterflies eat bananas?
Butterflies are particularly fond of oranges, grapefruits, cantelope, strawberries, peaches, nectarines, kiwi, apples, watermelon, and bananas, especially mushy bananas that have been stored in the freezer and then thawed. Some species love a “brew” of rotting fruit, molasses, beer, and brown sugar.
