Hornet hornets may often be black and white. There is also a related genus of Asian nocturnal vespines, "Provespa", which are referred to as "night wasps" or "night hornets", though they are not true hornets. Some other large wasps are sometimes referred to as hornets, most notably the bald-faced hornet ("Dolichovespula maculata") found in North America. It is set apart by its black and ivory coloration. The name "hornet" is used for this and related species primarily because of their habit of making aerial nests (similar to the true hornets) rather than subterranean nests. Another example is the Australian hornet ("Abispa
Insect diuretic hormones The complex is only present in lepidopteran larvae and some beetle species. Little is known about the hormonal control of fluid uptake by the cryptonephric complex, which is certain to play an important role in the species in which it occurs. First three letters of genus added to first two letters of the species name. For example, a 37-residue diuretic peptide from Tenebrio molitor will be named Tenmo-DH37. Insect diuretic hormones Insect diuretic hormones are hormones that regulate water balance through diuretic action. The insect excretory system, responsible for regulating water balance in the insect, comprises the Malpighian tubules and
