In 3 days ~10% in a week ~30%
Andrena marginata, sometimes called the small scabious mining bee is a species of the sand bee (Andrena) genus. This species is present in most of Europe and in the East Palaearctic. It can mainly be found in acidic or calcareous grasslands, moors, heaths, moorland edges and woodland, where Devil's-bit scabious plants occur.
Andrena marginata can reach a body length of about 11 mm (0.43 in). The basic body color of these medium-sized mining bees is black or dark brown. In the males the dark color is widespread on the hind body, only the second and third tergites are partially orange colored. They are slimmer, with denser body hairs than the female. The male shows a yellowish-white mouth shield.
The females of A. marginata occur in different colour forms. Usually the females have strongly hairs and a special pollen basket on hind legs. Moreover, in the females the hind body lacks hairs and they are black only on the first tergite (hind body segment), while other tergites are orange colored. Some females are predominantly orange. However more or less completely black or dark individuals can be found in both sexes.

It is the 301st most-seen of the 580 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.
July and August
In those months about 10% of wildlife watchers report a Small Scabious Mining Bee in Warsaw on a given day, against under 5% in September to June, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Small Scabious Mining Bee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Warsaw, in our data

GBIF citizen-science records
It is estimated from how often the Small Scabious Mining Bee is recorded against all the insects logged in Warsaw (16 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.
