The Lepidoptera have developed a wide variety of morphological wing-coupling mechanisms in the imago which render these taxa "functionally dipterous" (two winged). [33] All but the most basal forms exhibit this wing coupling. [ 34 ]
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 zoomed in view of the wing scales on a Aglais io, or peacock butterfly. Butterfly adults are characterized by their four scale-covered wings, which give the Lepidoptera their name (Ancient Greek λεπίς lepís, scale + πτερόν pterón, wing).
The principal cells of the wing used in classification are the discal, anal and second basal cells. The most encountered terms used in Diptera identification keys are:– cell cup. Also called the posterior cubital cell and often called the anal cell. The form of the cell cup is an important character. costal break. These frequently occur ...
The insect order Lepidoptera consists of moths and butterflies (43 superfamilies). [1] Most moths are night-flying, while the butterflies (superfamily Papilionoidea ) are the mainly day-flying. Within Lepidoptera as a whole, the groups listed below before Glossata contain a few basal families accounting for less than 200 species; the bulk of ...
Line of wing folding – Some species, including Vespidae, the forewing are longitudinally folded along the 'line of wing folding' at rest. Pterostigma – is present for some species. The forward margin of the hindwing bears a number of hooked bristles, or " hamuli ", which lock onto the forewing, keeping them held together.
The majority of insects have two pairs of wings. Flies possess only one set of lift-generating wings and one set of halteres. The order name for flies, "Diptera", literally means "two wings", but there is another order of insect which has evolved flight with only two wings: strepsipterans, or stylops; [2] they are the only other organisms that possess two wings and two halteres.

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.
