The name Tetragnatha is derived from Greek, tetra- a numerical prefix referring to four and gnatha meaning jaw.

Evolution to cursorial behavior occurred long ago in a few different species, the most studied being those found on the Hawaiian islands.

[6] Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.

Tetragnatha species are hard to separate from each other without a microscope to scrutinize the genitalia of a mature individual.

[7] Hawaiian Tetragnatha appear to distinguish each other via highly specific chemical compounds in their silk.
