Butterfly

Butterflies are part of the class of Insects in the order Lepidoptera. Moths are also included in this order. Adults butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprise the true butterflies (superfamily Papilionoidea), the skippers (superfamily Hesperioidea) and the moth-butterflies (superfamily Hedyloidea). Other families within Lepidoptera are referred to as moths. Butterfly fossils date to the mid Eocene epoch, 40–50 million years ago.[1] Butterflies exhibit polymorphism, mimicry and aposematism. Some, like the Monarch, will migrate over long distances. Some butterflies have parasitic relationships with organisms including protozoans, flies, ants, other invertebrates, and vertebrates. [2] [3] Some species are pests because in their larval stages they can damage domestic crops or trees; however, some species are agents of pollination of some plants, and caterpillars of a few butterflies (e.g., Harvesters) eat harmful insects. Culturally, butterflies are a popular motif in the visual and literary arts.
