Some water striders have wings present on the dorsal side of their thorax, while other species of Gerridae do not, particularly Halobates. Water striders experience wing length polymorphism that has affected their flight ability and evolved in a phylogenetic manner where populations are either long-winged, wing-dimorphic, or short-winged.

Water striders have the ability to move quickly on the water surface and have hydrophobic legs. On average, a water strider can move 1.5 metre per second by paddling forward with the middle pair of legs while the forelegs and hind legs act as a rudder. Waters striders also have the ability to stand effortlessly on water due to their non-wetting ...
Aquarius remigis, known as the common water strider, is a species of aquatic bug. [3] [4] It was formerly known as Gerris remigis, but the subgenus Aquarius was elevated to generic rank in 1990 on the basis of phylogenetic analysis. [5] [6] Aquarius remigis is found throughout North America, but is most prevalent in the mid-west of the United ...
"Moving of mating Water Striders (Gerris argentatus), weigh about 0.00002 lb created surface waves in a pond. The striders are out of focus (on purpose), but you could see their shadows, the hairs at their legs and the sun reflected from their footprints" - Brocken Inaglory. The ripples attract predators.
As striders increase in size, their legs become proportionately longer, with Gigantometra gigas having a length of over 20 cm requiring a surface tension force of about 40 millinewtons. Water striders generate thrust by shedding vortices in the water: a series of U-shaped vortex filaments is created during the power stroke. The two free ends of ...
Gerris buenoi is a species of water strider that belongs to the family Gerridae.It was first identified in 1911 and is native to continental USA and Canada. [1] Individuals of this species are small in size and have modified appendages, allowing them to float and "skate" along the surface of the water.
Telmatrechus is an extinct heteropteran genus in the water strider family Gerridae which is solely known from Early Eocene sediments exposed in western North America. the genus contains three described species, the type species Telmatrechus parallelus, plus Telmatrechus defunctus, and Telmatrechus stali.
Aquarius is a genus of water striders found predominantly in the northern hemisphere. Formerly a subgenus, Aquarius was elevated to generic rank in 1990 on the basis of phylogenetic analysis. [ 1 ] [ 2 ] These are among the world's largest water striders, with females averaging 12–17 mm (0.47–0.67 in) long and males roughly 10–30% smaller ...
