The butterflies form the clade Rhopalocera, which is composed of three superfamilies: Hedyloidea (the moth butterfly family Hedylidae), the Hesperioidea (the skipper family Hesperiidae), and the Papilionoidea (the true butterfly families Papilionidae, Pieridae, Nymphalidae, Lycaenidae, and Riodinidae). All of these families are monophyletic.
They evolved about the time that flowering plants underwent an expansive adaptive radiation in the mid-Cretaceous, and the Gelechioidea that evolved at this time also have great diversity. Whether the processes involved co-evolution or sequential evolution, the diversity of the Lepidoptera and the angiosperms increased together.
Possibly the original butter-fly. [6] A male brimstone (Gonepteryx rhamni) in flight.The Oxford English Dictionary derives the word straightforwardly from Old English butorflēoge, butter-fly; similar names in Old Dutch and Old High German show that the name is ancient, but modern Dutch and German use different words (vlinder and Schmetterling) and the common name often varies substantially ...
National Geographic's Ed Yong says Cooper's research supports a newer theory about the flightless bird family: that they "evolved from small, flying birds that flapped their way between continents ...
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 elusive animals were discovered in Ecuador after extensive searching, researchers said.
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 ...
Flapping flight is limited by the size and muscle force of a wing. Even while using the correct model of arboreal or cursorial, protobirds' wings were not able to sustain flight, but they did most likely gain the behaviors needed for the arboreal or cursorial model like today's birds do when hatched. There are similar steps between the two. [19]
