The Norwegian wasp (Dolichovespula norwegica) is a species of eusocial wasp. It is common in Scandinavia and can also be found in Scotland and other areas in Britain and Ireland. Often known for being a tree wasp, it nests in low branches and bushes and feeds on insects. It also obtains nectar from blueberry and snowberry flowers. Although D. norwegica is rarely considered a pest in the past, a few cases of pest problems relating to them have been reported. The species is not endangered.
D. norwegica is placed in the family Vespidae and the genus Dolichovespula. Based on recent studies on mitochondrial genes, Dolichovespula and Vespula are monophyletic, meaning they descended from common ancestors. Two species groups, maculata and norwegica, form the Dolichovespula clade. While the maculata has physical attributes such as pronotal striae, emarginated apices of the seventh metasomal sternum in males, and aedeagal medial lobes, D. norwegica females have long oculomalar space and lateroanterior clypeal angles with less prominent semicircular projections.
In the past, D. norwegica and D. albida, the Arctic yellowjacket from northern North America, were considered... Wikipedia →

With luck
About 10% of wildlife watchers report a Norwegian Wasp sighting in Denali National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 36 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Norwegian Wasp in Denali National Park on a given day, against under 5% in March–May and September–October, the lowest months. November to February have too few records to rate.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Norwegian Wasp sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Norwegian Wasp sightings, Denali National Park ranks 2nd at about 10%. The best odds are in Wrangell-St. Elias National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Norwegian Wasp is recorded against all the insects logged in Denali National Park (7 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.
