File:Rhagovelia whirling in a swarm.webm, Rhagovelia can be gregarious and form swarms. Morton Arboretum, Illinois Evolution Origins The origins of the genus are among water striders of Veliidae family without propelling fans on their legs. Evolution from water striders Genes 'geisha' and 'mother-of-geisha' The duplication of genes, called by researchers 'geisha' and 'mother-of-geisha', caused evolutionary creation of propelling fans on middle pair of water strider's legs which in its turn has made able for species in the genus to walk across more fast-flowing and turbulent streams.

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 ...

CRC Press
The CRC Press, LLC is an American publishing group that specializes in producing technical books. Many of their books relate to engineering, science and mathematics. Their scope also includes books on business, forensics and information technology. CRC Press is now a division of Taylor & Francis, itself a subsidiary of Informa. History The CRC Press was founded as the Chemical Rubber Company (CRC) in 1903 by brothers Arthur, Leo and Emanuel Friedman in Cleveland, Ohio, based on an earlier enterprise by Arthur, who had begun selling rubber laboratory aprons in 1900. The company gradually expanded to include sales of laboratory equipment to chemists. In 1913 the CRC offered a short (116-page) manual called the ''Rubber Handbook'' as an incentive for any purchase of a dozen aprons. Since then the ''Rubber Handbook'' has evolved into the CRC's flagship book, the '' CRC Handbook of Chemistry and Physics''. In 1964, Chemical Rubber decided to focus on its publishing ventures ...
