Origin: Formed within English, by compounding; modelled on a Latin lexical item. Etymons: water n., measurer n.

Etymology: < water n. + measurer n., after scientific Latin Hydrometra, genus name ( P. A. Latreille Précis des caractères génétiques des insectes (1796) 86), though used more broadly (including pond skaters) by J. C. Fabricius ( Systema rhyngotorum (1803) 256); < ancient Greek ὑδρο- , ὕδωρ water (see hydro- comb. form) + μέτρον measure: see metre n.¹).

Any of various predatory heteropteran bugs of the family Hydrometridae, esp. the genus Hydrometra, having a long narrow body with fragile legs and living on the surface film of water; also (North American) called marsh treader. Also (U.S.): a pond skater (family Gerridae).
