Vespula alascensis, also referred to as Alaska yellowjacket or American yellowjacket, is a species of yellowjacket that inhabits North America. Although it was named in 1870, it was, until 2010, treated as a taxonomic synonym of a related species, Vespula vulgaris, but is now recognized as a distinct taxon. Generally it nests in the ground.

Rare
Under 5% of wildlife watchers report an American Yellowjacket sighting in Montreal on a given day, based on 42 verified sightings from GBIF citizen-science data. It is the 216th most-seen of the 926 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August to October
In those months about 10% of wildlife watchers report an American Yellowjacket in Montreal on a given day, against under 5% in November to July, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most American Yellowjacket sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 9
Of the 9 cities where we can rate American Yellowjacket sightings, Montreal ranks 6th at under 5%. The best odds are in Anchorage (United States, about 20%), Seattle (United States, about 10%) and Portland (United States, about 10%).
Same genus: Vespula
The closest relatives of the American Yellowjacket that you can see in Montreal (genus Vespula, Ground Yellowjackets) are German Yellowjacket (about 10%) and Eastern Yellowjacket (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the American Yellowjacket is recorded against all the insects logged in Montreal (42 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.
