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.

GBIF citizen-science records
It is estimated from how often the American Yellowjacket is recorded against all the insects logged in Acadia National Park (34 verified sightings from 2019 to 2026), 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.
