Aedes vexans, commonly known as the inland floodwater mosquito or tomguito, is a widespread and frequently encountered pest mosquito with a cosmopolitan distribution, occurring across North America, Europe, Asia, and Africa.
The adult female A. vexans is characterized by a bandless proboscis with white ventral scales, short, brown scales on the scutum, and B-shaped markings (when viewed from the side) on each abdominal tergite. Only females take blood meals, showing a preference for humans and cattle, while males feed exclusively on nectar, honeydew, and sap—sources that females also utilize, though infrequently. This species is commonly found in habitats such as grassy pools, partially shaded woodland pools, roadside ditches, and cultivated fields.
After a blood meal, the female A. vexans deposits her eggs in areas prone to flooding, where they remain dormant until inundated, triggering hatching. In temperate regions, larvae are present from April to September, and adults are active from May to October.
A. vexans is a recognized vector for several pathogens: Dirofilaria immitis (dog heartworm), transmitted to canines. Tahyna... Wikipedia →

It is the 295th most-seen of the 390 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.
August
In that month about 10% of wildlife watchers report an Inland Floodwater Mosquito in Edmonton on a given day, against under 5% in September to July, the lowest months.
Among the best

GBIF citizen-science records
It is estimated from how often the Inland Floodwater Mosquito is recorded against all the insects logged in Edmonton (7 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.
