They are generally small, long-legged insects and the body length of most species is between 2 and 12 mm (0.08–0.47 in). A few are between 12 and 25 mm (0.47–0.98 in). [ 5 ] Among widespread genera, the North Hemisphere Aquarius includes the largest species, generally exceeding 12 mm (0.47 in), at least among females, and the largest ...

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.
Gerris swakopensis is an Afrotropical species of true bug. Common names include pond skater and water strider. [2] [3] It is aquatic, found in habitats with standing freshwater, such as ponds, pools, and backwaters of streams. [2]
The Hox gene "ultrabithorax" lengthens legs in insects. If its pool should dry out during a drought , a water strider will travel overland to find wetter pastures to settle in. [ 3 ] [ 5 ] [ 6 ] The front pair of legs of a water strider do not act as a rudder - they are very short and are held up in the air, ready to grab prey.

Gerrinae are marine insects and are found closer to inland waters. They prefer slow-moving ponds and streams to complement their natural ability. They can be commonly found throughout the Americas, Europe, and temperate Asia. While they are sociable, these insects prefer not to live in close, compact schools. [5] [6]
