The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, water gliders, water skimmers or puddle flies.
The Ochteroidea (infraorder Nepomorpha are also found in shore habitat, while the Gerromorpha are actually most often encountered running around on the water surface, being kept from sinking by surface tension and their water-repellent legs. Well-known members of the Gerromorpha are the namesake Gerridae (water striders).
Water striders, and more specifically those that fall under the genus Gerris are a model organism for studying sexual conflict as they have clear costs associated with their actions. They have great use as a control group when comparing to other organisms where it is more unclear as what is occurring.
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.
Water striders vary in length ranging between 8 millimetres (0.31 in) and 10 mm (0.39 in) in size. Their body shape is very slender and elongated. They have six legs ; the first pair is short and stubby while the other two pairs are thin and elongated which are used for moving over the water surface which we call "walking on water".
The pondskaters or water striders (Gerridae) are also associated with water, but use the surface tension of standing water to keep them above the surface; [44] they include the sea skaters in the genus Halobates, the only truly marine group of insects.

'Breaking in' your shoes in reality doesn't mean letting your shoes get used to the shape of your foot -- in fact it's quite the opposite: Your feet are going to be the ones working to adjust size ...
Members of the Gerrinae subfamily are characterized by having long slender bodies. Typically, juvenile gerrini range from a lengths of 1-13 mm, widths of 0.5-3 mm. Adult lengths are 4-17 mm, widths 1-4 mm. Noteably, these striders share similar sizes with the Cylindrostethinae and Ptilomerinae, subfamilies within the Gerridae family. [4]
