Elmidae, commonly known as riffle beetles, is a family of beetles in the superfamily Byrrhoidea described by John Curtis in 1830. Both adults and larvae are usually aquatic, living under rocks in fast-flowing shallow areas of streams, such as riffles, feeding on algae and biofilms.{{Citation|last=White|first=D.S.|title=Coleoptera (Beetles) in Aquatic Ecosystems|date=2009|url=https://linkinghub.elsevier.com/retrieve/pii/B9780123706263001605|encyclopedia=Encyclopedia of Inland Waters|pages=144–156|publisher=Elsevier|language=en|doi=10.1016/b978-012370626-3.00160-5|isbn=978-0-12-370626-3|access-date=2020-09-30}} There are more than 150 genera and 1,500 described species in Elmidae. The oldest record of the group is Cretohypsilara from the Cenomanian aged Burmese amber.{{Cite journal|last1=Cai|first1=Chenyang|last2=Maier|first2=Crystal A.|last3=Huang|first3=Diying|date=2018-09-01|title=A new riffle beetle in Upper Cretaceous amber from northern Myanmar (Coleoptera: Elmidae)|url=http://www.sciencedirect.com/science/article/pii/S0195667117302343|journal=Cretaceous Research|language=en|volume=89|pages=154–159|doi=10.1016/j.cretres.2018.03.022|s2cid=135138679 |issn=0195-6671}}
