Evolution
Origins
The origins of the genus are among water striders of Veliidae family without propelling fans on their legs.
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.[6]
