However, despite the shortcomings of the haplodiploidy hypothesis, it is still considered to have some importance. For example, many bees have female-biased sex ratios and/or invest less in or kill males. Analysis has shown that in Hymenoptera, the ancestral female was monogamous in each of the eight independent cases where eusociality evolved. [2]
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 ]
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 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 ]
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.
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 superfamily Apoidea is a major group (of over 30 000 species) within the Hymenoptera, which includes two traditionally recognized lineages, the "sphecoid" wasps, and the bees. Molecular phylogeny demonstrates that the bees arose from within the traditional " Crabronidae ", so that grouping is paraphyletic , and this has led to a ...
