From Portugal through Europe, Asia Minor and the Caucasus to Central Asia; north to Ireland and central Scotland, crosses the Arctic Circle in Scandinavia, in Norway up to 63 ° N, in Sweden up to 66 ° N, in Finland up to 67.5 ° N, in Russia up to Karelia and Kirov. In the south of the distribution area the species was often mixed up with Hylaeus deceptorius (BENOIST, 1959), so that the southern border is not unequivocally established – according to current knowledge, south to Sicily, Crete, Lebanon and northern Iran. Widespread in central Europe, from the plains to the higher elevations of the low mountain ranges and in the Alps. In central Europe very common and most common species of the genus.
As a pronounced ubiquist, the species occurs in a wide variety of habitats, both in dry and more humid locations, e.g. along forest edges, on clearings and clearcuts, in field hedges, in blackberry bushes, in sand, gravel and clay pits, on railway embankments, regularly also in residential areas in gardens, parks and on ruderal...

Rare
Under 5% of wildlife watchers report a Common Masked Bee sighting in London on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1153rd most-seen of the 1504 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 a Common Masked Bee in London on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Common Masked Bee sightings, London ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Birmingham (United Kingdom, under 5%) and Paris (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Masked Bee is recorded against all the insects logged in London (8 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.
