Brachycaudus rumexicolens, the short tailed sorrel aphid, is an aphid in the genus Brachycaudus that feeds on Polygonaceae, and ranges almost completely worldwide minus Antarctica. [1]
this aphid is found primarily on Rumex species in the United States, but can also be found on many other plants in the Polygonaceae. [1]
This species was introduced to Australia in 1998 where it has been used to wipe out a nonnative dock species. [2]
This species has two color forms, the North American color form is yellowish green, while the other ones worldwide are brown in coloration. [1]
The other defining features are that it is the size of a pinhead, has small, multi segmented, antenna, and short siphuncui (which is why its called Short tailed). [1]
