Due to their great aesthetic value and their transformation of metamorphosis that they undergo in their life cycle, butterflies are possibly one of the groups of insects most appreciated by naturalists and the general public. There are butterflies of many colors and sizes and, unlike their sisters the moths, they tend to have daytime activity. Adult Lepidopterans (which also include moths) have a lick-sucking mouthpart called a spirit-tube, which serves to feed on the nectar of flowers. This characteristic makes them insects that play a fundamental role in plant-animal interactions, and therefore pollination. Like the rest of the groups of pollinators, very important declines have also been registered in their populations in recent decades, which has led them to gain special attention not only for the fact that they are very efficient pollinators but also for being excellent bioindicators of ecosystem health.
