Families These three families belong to the superfamily Gerroidea: * Gerridae Leach, 1815 (water striders) * Hermatobatidae Coutière & Martin, 1901 * Veliidae Veliidae is a family of gregarious predatory insects in the suborder Heteroptera.

Gerromorpha
The Gerromorpha comprise an infraorder of insects in the "true bug" 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 water-repellent legs. Well-known members of the Gerromorpha are the namesake Gerridae (water striders). Systematics The eight family families usually recognized are arranged in four superfamilies. The two small or monotypic ones of these are 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) ** Mesoveliidae * Hebroidea – velvet bugs ** Hebridae ( Hyrcaninae might arguably be ...

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, or water skimmers. Consistent with the classification of the Gerridae as true bugs (i.e., suborder Heteroptera), gerrids have mouthparts evolved for piercing and sucking, and distinguish themselves by having the unusual ability to walk on water, making them pleuston (surface-living) animals. They are anatomically built to transfer their weight to be able to run on top of the water's surface. As a result, one could likely find water striders present in any pond, river, or lake. Over 1,700 species of gerrids have been described, 10% of them being marine. While 90% of the Gerridae 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 Buchanan-White collected several different species during the Cha ...

Veliidae
Veliidae is a 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. The genus ''Rhagovelia'' is also referred to as a ripple bug. Veliidae have a specialized body plan that allows them to walk on water and are neuston. Gerridae is another closely related group that is also neuston and both are in the 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. Life cycle Like all Heteroptera, the Veliidae go through an egg, nymph and adult stage. They have four or five nymphal instars. Both the adults and nymphs live together gregariously, in loose communities and can often be found in large groups. Eggs are usually laid underwater ...

Semiaquatic
In biology, semiaquatic can refer to various types of animals that spend part of their time in water, or plants that naturally grow partially submerged in water. Examples 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 frogs such as fire-bellied toads and wood frogs. ** Some reptiles such as crocodilians, turtles, water snakes and marine iguanas. ** Penguins. ** Some rodents such as beavers, muskrats and capybaras. **Some insectivorous mammals such as desmans, water shrews and platypuses. ** Some carnivoran mammals, including seals, polar bears and otters. ** Hippopotamuses. * Semiterrestrial echinoderms of the intertidal zone, such as the "cliff-clinging" sea urchin ''Colobocentrotus atratus'' and the starfish '' Pisaster ochraceus'' ...

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.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as Ant, ants, Bee, bees, Beetle, beetles, or Butterfly, butterflies. In some variations of English, all Terrestrial animal, terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the Colloquialism, colloquial understanding of ''bug''.

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 by the presence of three tarsal segments on all the legs and with pre-apical claws only on the fore-tarsi. T ...
