Gerroidea
Gerroidea is a superfamily of semiaquatic bugs in the order Hemiptera. There are at least 3 families and more than 2,000 described species in Gerroidea. Families These three families belong to the superfamily Gerroidea: * Gerridae Leach, 1815 (water striders) * Hermatobatidae Coutière & Martin, 1901 * Veliidae Veliidae is a family (biology), family of gregarious predatory insects in the suborder Heteroptera.

Gerromorpha
The Gerromorpha comprise an infraorder of insects in the "true bug" order (biology), order Hemiptera. These "typical" bugs (suborder Heteroptera) are commonly called semiaquatic bugs or shore-inhabiting bugs. The Ochteroidea (infraorder Nepomorpha are also found in shore habitat, while the Gerromorpha are actually most often encountered running around on the water surface, being kept from sinking by surface tension and their hydrophobic, water-repellent legs. Well-known members of the Gerromorpha are the namesake Gerridae (water striders). Systematics The eight family (biology), family families usually recognized are arranged in four Superfamily (zoology), superfamilies. The two small or monotypic ones of these are basal (evolution), basal lineages; the two larger ones form a more advanced clade. The phylogenetic sequence of superfamilies and families of the Gerromorpha is:ToL (1995) ;Mesovelioidea – water treaders * Madeoveliidae (sometimes included in Mesoveliidae) * Mesov ...

Gerridae P1060231b
The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, water gliders, water skimmers or puddle flies. They are true bugs of the suborder Heteroptera and have mouthparts evolved for piercing and sucking. A distinguishing feature is the ability to move on top of the water's surface, making them pleuston (surface-living) animals. They can be found on most ponds, rivers or lakes, and over 1,700 species of gerrids have been described, 10% of them being marine. While 90% of gerrids are freshwater bugs, the oceanic ''Halobates'' makes the family quite exceptional among insects. The genus ''Halobates'' was first heavily studied between 1822 and 1883 when Francis Buchanan White collected several different species during the Challenger Expedition. Around this time, Eschscholtz discovered three species of the Gerridae, bringing attention to the species, though little of the ...

Veliidae
Veliidae is a family (biology), family of gregarious predatory insects in the suborder Heteroptera. They are commonly known as riffle bugs, small water striders, or broad-shouldered water striders because the segment immediately behind the head is wider than the rest of the abdomen. Species of the genus ''Rhagovelia'' are also referred to as ripple bugs. Veliidae have a specialized body plan that allows them to walk on water and are neuston. The family Gerridae is another closely related group that is also neuston and both are in the Taxonomic rank, superfamily Gerroidea. Veliidae are smaller however, between . They can be found on ponds, near lake shores, and in rivers worldwide. Some species can also be found on plants near water, in salt water or in mud flats. Description Veliidae are very similar to Gerridae. The most consistent characteristic used to separate these two families are internal Sex organ, genitalia differences, however external cues are usually sufficient to te ...

Semiaquatic
In biology, being semi-aquatic refers to various macroorganisms that live regularly in both aquatic and terrestrial environments. When referring to animals, the term describes those that actively spend part of their daily time in water (in which case they can also be called amphibious), or land animals that have spent at least one life stages (e.g. as eggs or larvae) in aquatic environments. When referring to plants, the term describes land plants whose roots have adapted well to tolerate regular, prolonged submersion in water, as well as emergent and (occasionally) floating-leaved aquatic plants that are only partially immersed in water. Examples of semi-aquatic animals and plants are given below. Semiaquatic animals Semiaquatic animals include: * Vertebrates ** Amphibious fish; also several types of normally fully aquatic fish such as the grunion and plainfin midshipman that spawn in the intertidal zone ** Some amphibians such as newts and salamanders, and some fr ...

Hemiptera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising more than 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is sometimes limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some varieties of English, all terrestrial arthropods (including non-insect arachnids and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. ...

Hermatobatidae
''Hermatobates'' is a genus of wingless marine bugs placed as the sole genus in the family Hermatobatidae that are sometimes known as coral-treaders. They are quite rare and known only from coral reefs in the Indo-Pacific region. During low tide, they move over the water surface not unlike the more familiar water-striders around coral atolls and reefs and stay submerged in reef crevices during high tide. The genus was described by the amateur entomologist Rev. George Carpenter in 1892 on the basis of a single specimen obtained from Mabuiag Island in the Torres Straits by Alfred Cort Haddon. The species was described as ''H. haddoni''. The species are very rare and difficult to observe in life. Most subsequent specimens in the genus have been captured using neuston drag nets, sometimes with artificial lights at night. They are differentiated from the striders in the Gerridae The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water ...
