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 ]
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]
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.
Today, however, much of this natural habitat has completely disappeared, along with the largest of the cats. There are currently three wild species of felines living on the continent. European Wildcat
Holometabolism stages in Hymenoptera. The Endopterygota are distinguished from the Exopterygota by the way in which their wings develop. [citation needed] Endopterygota (literally "internal winged forms") develop wings inside the body and undergo an elaborate metamorphosis involving a pupal stage. Exopterygota ("external winged forms") develop ...
