Nomioides minutissimus
In 3 days ~10% in a week ~30%
Nomioides minutissimus is a species of sweat bee in the family Halictidae. It is found throughout Europe, North Africa and South Asia. As of 2023, it is the only species of Nomioides found in Poland, and is one of the smallest bees in the country.
The species is about 3.5–4.5 mm long, and prefers to live in sandy soil with patches of uncovered sand and flowering plants. It is a polylectic or generalist pollinator, and some of the plants it has been known to visit include Conyza canadensis, Centaurea diffusa, Potentilla argentea, Erigeron annuus, Jasione montana, and various Thymus species, among others. The subspecies N. m. maurus, native to North Africa, has been observed to visit Herniaria fontanesi, Frankenia laevis, and Senecio and Campanula species.
Each bee digs its own nest, which has a circular opening about 2 mm in diameter. Each nest proceeds vertically down for about 13–22 cm until it reaches a lower blind passage. Starting past around 5 cm down, around 6–10 side passages branch off, traveling 1–8 cm laterally while sometimes sloping downwards. Tunnels from the side passages lead directly to the brood cells, which are around 5 mm in their longest diameter. Wikipedia →

Rare
Under 5% of wildlife watchers report a Nomioides minutissimus sighting in Warsaw on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 373rd 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.
June and July
In those months about 10% of wildlife watchers report a Nomioides minutissimus in Warsaw on a given day, against under 5% in August to May, the lowest months.
Only Warsaw, in our data
Warsaw is the only city on Wallace's Line with enough records to rate Nomioides minutissimus sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Nomioides minutissimus is recorded against all the insects logged in Warsaw (11 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.
