Corixa Punctata
The lesser waterboatman or lesser water boatman (''Corixa punctata'') is a water-dwelling insect of the order Hemiptera. Adults normally range in size from 5 to 15 mm long, and are found in ponds, lakes and sometimes even swimming pools. The boatman feeds on algae and dead plant material. They have long hind legs which they use to swim on top of water. These powerful legs are covered in tiny hairs which helps them float on the surface of the water. They breathe oxygen by trapping air beneath their wing cases when they are on the surface as the oxygen is trapped by tiny hairs. They use trapped air in their physical gill to convert water-borne sounds into airborne sounds that they can hear. They are similar to ''Notonecta glauca'', the back swimmer by appearance, although these lesser waterboatman are herbivores and swim on their fronts. They are not related to ''Notonecta glauca'', back swimmer, nor to the European ''Micronecta scholtzi ''Micronecta scholtzi'', the lesse ...

Johann Karl Wilhelm Illiger
Johann Karl Wilhelm Illiger (19 November 1775 – 10 May 1813) was a German entomologist and zoologist. Illiger was the son of a merchant in Braunschweig. He studied under the entomologist Johann Christian Ludwig Hellwig, Johann Hellwig, and later worked on the zoological collections of Johann Centurius Hoffmannsegg. Illiger was professor and director of the "zoological museum" (which is the Natural History Museum, Berlin, Natural History Museum of Berlin in the present day) from its formation in 1810 until his death. He was the author of ''Prodromus systematis mammalium et avium'' (1811), which was an overhaul of the Carl Linnaeus, Linnaean system. It was a major influence on the adoption of the concept of the Family (biology), family. He also edited the ''Magazin für Insektenkunde'', widely known as "Illiger's Magazine". In 1811 he introduced the taxonomic order Proboscidea for elephants, the American Mastodon, American mastodon and the woolly mammoth. He also described the ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiptera
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.''

Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Notonecta Glauca
''Notonecta glauca'' (common backswimmer) is a species of aquatic insect, and a type of backswimmer. This species is found in large parts of Europe, North Africa, and east through Asia to Siberia and China. In much of its range it is the most common backswimmer species. It is also the most widespread and abundant of the four British backswimmers. ''Notonecta glauca'' are ''Hemiptera'' (true bug) predators, that are approximately 13–16 mm in length. Females have a larger body size compared to males. These water insects swim and rest on their back (hence their common name "backswimmer" or "water boatman") and are found under the water surface. ''Notonecta glauca'' supports itself under the water surface by using their front legs and mid legs and the back end of its abdomen and rest them on the water surface; They are able to stay under the water surface by water tension, also known as the air-water interface (surface tension). They use the hind legs as oars; these legs are fri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Back Swimmer
Notonectidae is a cosmopolitan family of aquatic insects in the order Hemiptera, commonly called backswimmers because they swim "upside down" (inverted). They are all predators and typically range from in length. They are similar in appearance to Corixidae (water boatmen), but can be separated by differences in their dorsal-ventral coloration, front legs, and predatory behavior. Their dorsum is convex, lightly colored without cross striations. Their front tarsi are not scoop-shaped and their hind legs are fringed for swimming. There are about 350 species in two subfamilies: Notonectinae with seven genera, and Anisopinae with four genera. Members in the former subfamily are often larger than those in the latter. Backswimmers swim on their backs, vigorously paddling with their long, hair-fringed hind legs and attack prey as large as tadpoles and small fish. They can inflict a painful "bite" on a human being, actually a stab with their sharp tubular mouthparts (proboscis). They ...

Micronecta Scholtzi
''Micronecta scholtzi'', the lesser water boatman, is a species of pygmy water boatman in the family Micronectidae. It was first described by Franz Xaver Fieber in 1860. They are some 2 mm long and are common in freshwater ponds and lakes across Europe, preferring stagnant to moderately moving water. In Central Europe, the genus '' Micronecta'' is represented by five species, as follows: *''Micronecta'' (''Dichaetonecta'') ''pusilla'' (Géza Horváth, 1895) *''Micronecta'' (''Dichaetonecta'') ''scholtzi'' ( Fieber, 1860) *''Micronecta'' (''Micronecta'') ''griseola'' Géza Horváth, 1899 *''Micronecta'' (''Micronecta'') ''minutissima'' (Linnaeus, 1758) *''Micronecta'' (''Micronecta'') ''poweri'' (Douglas & Scott, 1869) ''M. scholtzi'' is easily differentiated from other species in this genus by the twisted left paramere of the male genitalia, (see traumatic insemination) the short pronotum and a distinctive dark pattern on the head. Little is known of its habits and hab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
