In many insect species, the forewing and hindwing can be coupled together, which improves the aerodynamic efficiency of flight by joining the forewing and hindwing into one bigger wing. The most common coupling mechanism (e.g., Hymenoptera and Trichoptera ) is a row of small hooks on the forward margin of the hindwing, or " hamuli ", which lock ...
Rhopalosomatidae is a family of Hymenoptera containing about 68 extant species in four genera that are found worldwide. [1] Three fossil genera are known. [2] [3] Rhopalosoma poeyi female. The adults resemble ants and may be confused with them. They are yellowish with red or brown markings, but may be all brown in colour.
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, [ 2 ] [ 3 ] in addition to over 2,000 extinct ones. [ 4 ]
The more primitive groups have an enlarged lobe-like area near the basal posterior margin, i.e. at the base of the forewing, a jugum, that folds under the hindwing in flight. [31] [33] Other groups have a frenulum on the hindwing that hooks under a retinaculum on the forewing. [33]
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. Along with the frenulum, a spine at the base of the forward or costal edge of the hindwing, it forms a coupling mechanism for the front and rear wings of the moth.
The most common coupling mechanism (e.g., Hymenoptera and Trichoptera) is a row of small hooks on the forward margin of the hindwing, or "hamuli", which lock onto the forewing, keeping them held together (hamulate coupling).
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.
