What do butterflies eat and how?
Answers
Most adult butterflies drink nectar from flowers through their tongues, which function much like straws. A minority of butterflies almost never visits flowers, instead gaining sustenance from tree sap, rotting animal matter, and other organic material. Butterfly caterpillars almost all eat plant matter.

Butterfly caterpillars almost all eat plant matter. Mainly the caterpillars eat leaves, but some species eat seeds and seed pods while others specialize on flowers. Most species will eat only a small group of related plant species -- for example Pearl Crescent caterpillars will eat species of asters. Some species, such as Gray Hairstreaks, will eat a wide variety of plants and some will eat only a single plant species. Although they eat plants, very few butterfly caterpillars are agricultural pests and if caterpillars are destroying some of your garden plants, it is unlikely that they are butterflies (unless you planted those plants specifically to attract butterflies). The caterpillar of one North American butterfly,the Harvester, eats aphids.
