Butterfly A group of insects in the order Lepidoptera

Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers and the most recent analyses suggest it also contains the moth-butterflies. Butterfly fossils date to the Paleocene, which was about 56 million years ago.

William Harry Evans British entomologist

Brigadier William Harry Evans CSI CIE DSO was a lepidopterist and British Army officer who served in India. He documented the butterfly fauna of India, Burma and Ceylon in a series of articles in the Journal of the Bombay Natural History Society. Brigadier Evans was especially interested in the taxonomy and systematics of the butterfly families Lycaenidae and Hesperiidae an example being his A revision of the Arhopala group of Oriental Lycaenidae Bull. British Mus. , Ent., vol. 5: pp. 85–141 (1957).

John Evershed CIE FRS FRAS was an English astronomer. He was the first to observe radial motions in sunspots, a phenomenon known as the Evershed effect.
