Leptoconops (Leptoconops) Zherikhini
''Leptoconops'' (black gnat) is a midge genus in the family Ceratopogonidae. It has a mostly tropical or subtropical distribution worldwide, but some species occur as far north as Moscow region in Russia and the Yukon Territory in Canada. This genus is relictual, having had a pantropical distribution during the Cretaceous. The presence of ''Leptoconops'', along with '' Austroconops'', in ancient Lebanese amber makes these the earliest existing lineages of biting midges. Extinct species have also been described from amber from Siberia, New Jersey, Canada, Hungary, Sakhalin, France, and Spain. Adult ''Leptoconops'' females are diurnal feeders, and suck vertebrate blood. Adults of both sexes in some species rest by burying themselves in sand. Larvae feed on algae, fungi, and bacteria. They burrow in moist, usually saline, sand or mud of desert areas and coastal and inland beaches. Species ''Leptoconops'' contains the following species: *'' Leptoconops acer'' Clastrier, 1973 *'' ...

Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). The most abundant cells are red blood cells. These contain hemoglobin, which facilitates oxygen transport by reversibly binding to it, increasing its solubility. Jawed vertebrates have an adaptive immune system, based largely on white blood cells. White blood cells help to resist infections and parasites. Platelets are important in the clotting of blood. Blood is circulated around the body through blood vessels by the ...

Leptoconops Antiquus
''Leptoconops antiquus'' is an extinct species of biting midges belonging to the family Ceratopogonidae. This species was described from fossilized remains preserved in Lower Cretaceous amber from Lebanon. The species name ''antiquus'' (ancient) was given in reference to the great age of the fossil. References † † A dagger, obelisk, or obelus is a typographical mark that usually indicates a footnote if an asterisk has already been used. The symbol is also used to indicate death (of people) or extinction (of species or languages). It is one of the mo ...
