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 ...
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 ]
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.
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 Hymenopterida is a superorder of holometabolous (metamorphosing) insects . As originally circumscribed, it included Hymenoptera and the orders in Panorpida ( Mecoptera , Siphonaptera , Diptera , Trichoptera and Lepidoptera ). [ 1 ]
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).
This glossary of entomology describes terms used in the formal study of insect species by entomologists.. When present, elytra of the Staphylinidae are markedly abbreviate. This fly in the genus Scaptomyza has clearly visible rows of para-sagittal acrostichal bristles on its thorax the alitrunk of aculeate Hymenoptera comprises the three thoracic segments, plus the propodeum, which strictly ...
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]
