Butterflies are indicators of a healthy ecosystem. They are quintessential pollinators that promote the reproduction of flowering plant species by carrying pollen from one flower to another while feeding on their nectar. It is also known that an ecosystem with a high butterfly richness is likely to have a high richness in other insect groups. Butterflies are an important source of food for many species of birds, bats, and reptiles, so they also promote the presence of several vertebrate groups. Most probably, the more than 50 butterfly species in these secondary Andean forests would not exist without the restoration processes that have been developed in the upper Pance basin.
