The disease carrier evolved into a subspecies with some genetic differences from their common relative.

Navigating the London Underground can be a challenging task, exacerbated by the presence of various creatures, including rats, mice, and bothersome pigeons, amid the crowds of commuters. While these pests may elicit gasps from passengers, there is yet another threat to be vigilant about: a newly identified, bloodthirsty variety of mosquitoes.

What is the London Underground species of mosquito called?

This century-old specimen represents a subtype of the mosquito commonly encountered in the British Isles, known as Culex pipien molestus. Its presence became anecdotal knowledge during World War II when London residents sought refuge from air raids in the subterranean tunnels of the Tube. It was those individuals seeking shelter who found themselves targeted by these formidable arthropods armed with proboscis-like feeding apparatus.

Why are they different?

The absence of sunlight in this subterranean region of London creates an ideal environment for these mosquitoes to proliferate. With a readily available source of sustenance in the form of humans, their population is unlikely to dwindle anytime in the foreseeable future.

These flying insects have acquired distinct genetic characteristics, leading to their unique scientific classification, setting them apart from their counterparts on the surface.

The Tube variant, ‘molestus,’ exhibits a notable preference for feeding on humans and mammals, whereas the surface-dwelling variant, ‘pipiens,’ is primarily associated with avian hosts. However, the most significant distinction lies in their breeding patterns: the subterranean species can reproduce year-round due to the consistently warmer climate and the abundant food resources available below ground.

Are they dangerous?

It is unlikely that these mosquitoes pose a significant risk, as they are closely related to the common mosquito species found throughout Europe. The primary concern may be an immune response triggered by their bites on the human body. Though some people are allergic to them caused by proteins in the saliva of the insect, known as Skeeter syndrome. Speak to a doctor if you suspect a reaction.
