Pierre André Latreille
Pierre André Latreille (; 29 November 1762 – 6 February 1833) was a French zoologist, specialising in arthropods. Having trained as a Roman Catholic priest before the French Revolution, Latreille was imprisoned, and only regained his freedom after recognising a rare beetle species he found in the prison, ''Necrobia ruficollis''. He published his first important work in 1796 (), and was eventually employed by the . His foresighted work on arthropod systematics and taxonomy gained him respect and accolades, including being asked to write the volume on arthropods for George Cuvier's monumental work, , the only part not by Cuvier himself. Latreille was considered the foremost entomologist of his time, and was described by one of his pupils as "the prince of entomologists". Biography Early life Pierre André Latreille was born on 29 November 1762 in the town of Brive, then in the province of Limousin, as the illegitimate child of Jean Joseph Sahuguet d'Amarzit, général ...

Aquatic Insect
Aquatic insects or water insects live some portion of their life cycle in the water. They feed in the same ways as other insects. Some ''diving'' insects, such as predatory diving beetles, can hunt for food underwater where land-living insects cannot compete. Breathing One problem that aquatic insects must overcome is how to get oxygen while they are under water. Almost all animals require a source of oxygen to live. Insects draw air into their bodies through spiracles, holes found along the sides of the abdomen. These spiracles are connected to tracheal tubes where oxygen can be absorbed. All aquatic insects have become adapted to their environment with the specialization of these structures ;Aquatic adaptations # Simple diffusion over a relatively thin integument # Temporary use of an air bubble # Extraction of oxygen from water using a plastron or blood gill # Storage of oxygen in hemoglobin molecules in hemolymph # Taking oxygen from surface via breathing tubes ( siph ...

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.''

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 ...

Velia Caprai
''Velia caprai'', known as the water cricket, is a species of aquatic bug found in Europe. It grows to a length of and is stouter than pond skaters of the family Gerridae. It is distasteful to predatory fish, engages in kleptoparasitism, and can travel at twice its normal speed by spitting on the water surface. Description The adult insect grows to a length of . Members of the family Veliidae resemble the pond skaters of the family Gerridae, but with stouter middle and hind legs, and a generally stouter appearance. Ecology ''Velia caprai'' has a chemical defence mechanism which is often able to prevent predation. It is so distasteful to brown trout (''Salmo trutta'') that the fish will spit out any ''Velia caprai'' it takes without causing them any damage. Behaviour ''Velia caprai'' is subject to kleptoparasitism. In one study, whenever it took prey heavier than , other bugs of the same species joined it and successfully ate parts of the prey.
