Gerrinae is a subfamily of water strider. This subfamily includes the largest and most best-known group of Gerridae. They are also a phylogenetic subfamily made up of two tribes, and ~14 genera. [1][2]
Description
[edit]Like all water striders, Gerrinae are able to walk on water using hydrophobic microhairs. Their bodies also consist of two antennae, a narrow thorax, and six appendages. [3]
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]
Habitat
[edit]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]
Their most common source of prey are smaller insects. They will usually only go after anything that is helplessly stuck in the water. There are even cases of them resorting to cannibalism during food shortages, young nymphs and weaker adults often fall victim to this.[6][7]
