About 160,000 species of butterflies and moths are already known, but scientists believe that a similar number still remain undiscovered. Identification and characterization of these species can be complicated by the fact that each species has an immature caterpillar and a mature butterfly form, as well as the reliance on the physical appearance for classification.
