Butterfly evolution is the origin and diversification of butterflies through geologic time and over a large portion of the Earth's surface. The earliest known butterfly fossils are from the mid Eocene epoch, between 40-50 million years ago.
The butterfly was sometimes depicted with the maw of a jaguar, and some species were considered to be the reincarnations of the souls of dead warriors. The close association of butterflies with fire and warfare persisted into the Aztec civilisation; evidence of similar jaguar-butterfly images has been found among the Zapotec and Maya civilisations.
With the evolution of the Ditrysia in the mid-Cretaceous, there was a major reproductive change. The Ditrysia, which comprise 98% of the Lepidoptera, have two separate openings for reproduction in the females (as well as a third opening for excretion), one for mating, and one for laying eggs.
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
A Lepidoptera specimen drawer in a museum collection in Poland Another Lepidoptera specimen drawer in a museum collection in Poland. Lepidopterology (from Ancient Greek λεπίδος (lepídos) 'scale' πτερόν (pterón) 'wing' and -λογία [1]) is a branch of entomology concerning the scientific study of moths and the two superfamilies of butterflies.
The butterfly has a wing length of 24.5 mm (1.0 in), and the specimen is complete, although the trailing edge of one hindwing was originally covered. [6] The upper surface of the animal is visible, and the legs can only barely be seen. The head is turned to one side, revealing the mouthparts as well as both antennae. [6]

Evolution has produced astonishing variety of appendages in insects, such as these antennae.. The most recent understanding of the evolution of insects is based on studies of the following branches of science: molecular biology, insect morphology, paleontology, insect taxonomy, evolution, embryology, bioinformatics and scientific computing.
