In 3 days ~10% in a week ~20%
Paykullia maculata is a species of fly in the subfamily Rhinophorinae first described by Carl Fredrik Fallén in 1815. This species can be found in most of Europe (Austria, Great Britain, Czech Republic, Denmark, France, Germany, Hungary, Ireland, Italy, Spain, Norway, Poland, Slovakia, Sweden, Switzerland, Netherlands) Habitats include wetlands, woodlands, parks and gardens.
Paykullia maculata can reach a length of 5–6 millimetres (0.20–0.24 in). The adults of this species are very variable, especially in size and in the pattern of wing markings. These small flies have a shining black body with bristly hair. The apical half of the wings show darkened veins and costal area.
Adults can be seen from May to September, with several generations. Usually they rest or run around on stones or among the foliage. The larvae are intestinal parasites of Porcellio scaber and Oniscus asellus, and woodlice from Protracheoniscus and Trachelipus genera. Wikipedia →

Rare
Under 5% of wildlife watchers report a Paykullia maculata sighting in Helsinki on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 553rd most-seen of the 838 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.
September and October
In those months about 10% of wildlife watchers report a Paykullia maculata in Helsinki on a given day, against under 5% in November to August, the lowest months.
Only Helsinki, in our data
Helsinki is the only city on Wallace's Line with enough records to rate Paykullia maculata sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Paykullia maculata is recorded against all the insects logged in Helsinki (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.
