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 →

GBIF citizen-science records
It is estimated from how often the Graphomya maculata is recorded against all the insects logged in Birmingham (10 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.
