Examples of frenulo-retinacular wing coupling in male and female moths Other groups of moth have a frenulum on the hindwing that hooks under a retinaculum on the forewing. [ 4 ] The retinaculum is a hook or tuft on the underside of the forewing of some moths .
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]
The terms are directly from Latin, in which hamus means "hook".The plural is hami.. Hamulus is the diminutive – hooklet or little hook. The plural is hamuli.. Adjectives are hamate and hamulate, as in "a hamulate wing-coupling", in which the wings of certain insects in flight are joined by hooking hamuli on one wing into folds on a matching wing.
Wing-coupling – Row of hooks on the leading edge of hindwing engage the hind margin of the forewing, strongly couple the wings in flight. Line of wing folding – Some species, including Vespidae, the forewing are longitudinally folded along the 'line of wing folding' at rest.
Butterfly adults are characterized by their four scale-covered wings, which give the Lepidoptera their name (Ancient Greek λεπίς lepís, scale + πτερόν pterón, wing). These scales give butterfly wings their colour: they are pigmented with melanins that give them blacks and browns, as well as uric acid derivatives and flavones that ...
Frenulo-retinacular wing coupling in male and female moths. Some four-winged insect orders, such as the Lepidoptera, have developed morphological wing coupling mechanisms in the imago which render these taxa functionally two-winged. [30] All but the most basal forms exhibit this wing-coupling. [31]
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 ...
