Aedes triseriatus
In 3 days ~10% in a week ~20%
Aedes triseriatus is a member of the true fly order (Diptera: Culicidae). It is called the eastern treehole mosquito due to its predilection towards breeding in stagnant water that is found in natural holding containers such as tree holes. It is native to the eastern United States and southern Canada and favors hardwood habitats. It has been found as far south as the Florida Keys, as far west as Idaho and Utah, and as far north as Quebec and Ontario. This species has not yet been found in Europe, but it has the potential to spread through international trade. In 2004, it was found in a shipment of tires travelling from Louisiana to France, but it was identified and targeted with insecticides that truncated its spread. It is a known vector of La Crosse encephalitis and canine heartworm disease. In the laboratory, it has been found to vector several other viruses including yellow fever, eastern encephalitis, Venezuelan encephalitis, and western encephalitis. Because of its potential for international spread and its proclivity for transmitting disease, monitoring the distribution of this species is essential.

Rare
Under 5% of wildlife watchers report an Eastern Treehole Mosquito sighting in Washington on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 1064th most-seen of the 1807 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 an Eastern Treehole Mosquito in Washington on a given day, so our monthly data shows no clear season.
Among the best
Of the 5 cities where we can rate Eastern Treehole Mosquito sightings, Washington ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Minneapolis [Saint Paul] (United States, under 5%) and Boston (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Eastern Treehole Mosquito is recorded against all the insects logged in Washington (16 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.
