Graphomya maculata
In 3 days ~10% in a week ~20%
Graphomya maculata is a species of fly. It is widespread and common in most parts of Europe and also occurs in North Africa including the Canary Islands. The thorax bears the same black and white pattern in both sexes. Females also have a black and white abdomen, while the male has orange colouration on the abdomen as seen in the picture.
While adults are not predatory and can be found nectaring on flowers in meadows, hedge rows, and roadside vegetation, the larvae are predatory, feeding in muddy pools and damp leaf litter. Wikipedia →

Rare
Under 5% of wildlife watchers report a Graphomya maculata sighting in London on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 753rd 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.
October
In that month about 10% of wildlife watchers report a Graphomya maculata in London on a given day, against under 5% in November to September, the lowest months.
Among the best
Of the 4 cities where we can rate Graphomya maculata sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Birmingham (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Graphomya maculata is recorded against all the insects logged in London (21 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.
