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] There are three different types of mechanisms – jugal, frenulo–retinacular, and amplexiform. [35]
Some four-winged insect orders, such as the Lepidoptera, have developed a wide variety of morphological wing coupling mechanisms in the imago which render these taxa as "functionally dipterous" (effectively two-winged) for efficient insect flight. [1] All but the most basal forms exhibit this wing coupling. [2]: 4266
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.
Volunteers scout out a meeting place and map out a 15-mile circle in which they count all the butterflies they see in one day. These counts give clues into the butterfly biodiversity of a particular region. The North American Butterfly Association also publishes the American Butterflies magazine quarterly. The magazine is currently 48 pages ...
Flexible wings were found to decrease the drag in flinging motion by up to 50% and further reduce the overall drag through the entire wing stroke when compared to rigid wings. [21] Bristles on the wing edges, as seen in Encarsia formosa, cause a porosity in the flow which augments and reduces the drag forces, at the cost of lower lift ...

At Flat Rock Brook Nature Center, New Jersey, United States. Its wingspan ranges from 62 to 88 mm (2.4 to 3.5 in). [2] It is characterized by its orange colour above with five black dashes near forewing base and several irregular black dashes at the base of the hindwing. In addition, two rows of black crescents run along the edges of the wings.
Hedylidae, the "American moth-butterflies", is a family of insects in the order Lepidoptera, formerly representing the superfamily Hedyloidea.They have traditionally been viewed as an extant sister group of the butterfly superfamily Papilionoidea, but a 2014 phylogenetic analysis has suggested Hedylidae is a subgroup of Papilionoidea, and not a sister group, and are more accurately referred to ...
