Aedes geniculatus
In 3 days ~10% in a week ~20%
Aedes geniculatus, also known as the tree hole mosquito, is closely related to the better known Asian tiger mosquito and is native to Europe and North Africa. After the Zika epidemic in 2016, it was mistakenly reported to Public Health England by members of the public, who were monitoring the spread of Zika-carrying mosquitoes in southern England following media reports of the spread of the Asian tiger mosquito.
Although it has not been observed in the wild as a disease vector, in laboratory tests, the tree hole mosquito can transmit yellow fever and chikungunya and so may be able to spread the Zika virus. Wikipedia →

Rare
Under 5% of wildlife watchers report a Tree Hole Mosquito sighting in London on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1153rd most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Tree Hole Mosquito in London on a given day, so our monthly data shows no clear season.
Among the best
Of the 3 cities where we can rate Tree Hole Mosquito sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Paris (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Tree Hole Mosquito is recorded against all the insects logged in London (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
