In 1998 a new breed of mosquito was discovered on which underground system?
London Underground mosquito London Underground mosquito The London Underground mosquito is a form of mosquito in the genus "Culex". It is found in the London Underground railway system as its name suggests, but has a worldwide distribution and long predates the existence of the London Underground. It was first described as a distinct species from Egyptian specimens by the biologist Peter Forsskål (1732–1763). He named this mosquito "Culex molestus" due to its voracious biting, but later biologists renamed it "Culex pipiens" f. "molestus" because there were no morphological differences between it and "Culex pipiens". Notably, this mosquito assaulted Londoners sleeping in the Underground
London Underground mosquito during the Blitz, although similar populations were long known. A study from 2004 analyzing DNA microsatellites suggested that "Culex molestus" is likely a distinct species from "Culex pipiens". However, a more recent paper from 2012 argues that it is more accurately 'a physiological and ecological variant of "Cx. pipiens" ' and should not be considered a distinct species. This mosquito, although first discovered in Egypt in the late 18th century, has been found in underground systems around the world. Some authors suggested that it adapted to human-made underground systems since the last century from local above-ground "Culex pipiens", but the
