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.
Insects that visit flowers are in search of pollen and nectar. Most flowers produce nectar just to attract pollinators. The higher the concentration of sugar in the nectar, the more attractive it is to pollinators. Nectar can also contain other useful compounds such as lipids, amino acids, vitamins, and minerals.
