The water boatmen, the single family of the hemipteran superfamily Corixoidea.

Corixidae

 

a family of water bugs. The body usually measures 5–6 mm. The tibiae of the front legs are shortened, and the feet are spoon-shaped. There are about 100 species, with 46 distributed in the USSR. The Corixidae live in small bodies of water and swim and fly well. They feed on plants, scraping off the surface tissues, and also completely sucking up seaweed filaments and particles of silt and detritus. The males can stridulate by rubbing their feet over the edges of the upper lip. When there are many Corixidae. the noise they produce becomes audible from the water.

New data is reported for the distribution of 18 species, of which two belong to the infraorder Nepomorpha: Corixidae: Heterocorixa and Notonectidae: Martarega', 16 belong to Gerromorpha: of which 12 belong to the family Gerridae: Metrobates, Tachygerris, Limnogonus (two species), Brachymetra, Neogerris, Potamobates, Trepobates (three species), Telmatometra, Rheumatobates', three belong to the family Veliidae: Rhagovelia, Microvelia (two species), and one to Mesoveliidae: Mesovelia.
Two subfamilies (Diaprepocorinae and Micronectinae) that belonged to the Corixidae were elevated to the rank family level of the Micronectidae and Diaprepocoridae by Nieser [32] and have been accepted at that position by other researchers [33-37].
These taxa were later replaced by stable zooplankton communities and many predators from the families Corixidae and Notonectidae.

When the salinity is lowest, the brine shrimp population decreases, not because it is unable to live in less salty water but because the populations of its predators increase, and these include water boatmen (family Corixidae), which are less tolerant of high salinity.
Insects included Odonata (Gomphidae, Macr omiidae), Megaloptera, Trichoptera, Plecoptera, Coleoptera (Haliplidae, Dytiscidae, Gyrinidae, Psephenidae, Dryopoidea), Ephemeroptera, Hemiptera (Corixidae, Belostomatidae, Veliidae), and Diptera (Tipulidae, Chironomidae).
