In 3 days ~10% in a week ~20%
Tephrochlamys rufiventris is a species of fly in the family Heleomyzidae. It is found in the Palearctic. The body length is 5 to 6 mm. The head has both setae and bristles on the gena. The thorax is characterized by the presence of setae on the propleura, a bare prothorax and metathoracic setae in a 0+3 arrangement, with the first pair of suture setae lying closer to the suture than to the second pair. The posterior and anterior metathoracic setae are almost the same length, and the hairs between them are placed in more than four rows. The wings have short and monochromatic pterostigmas and spine-like bristles on the costal vein longer than the hair. The middle pair of legs has one well-developed spur on each tibia. For terms see Morphology of Diptera.

Rare
Under 5% of wildlife watchers report a Tephrochlamys rufiventris sighting in London on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1394th 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.
December
In that month about 10% of wildlife watchers report a Tephrochlamys rufiventris in London on a given day, against under 5% in January to November, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Tephrochlamys rufiventris sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Tephrochlamys rufiventris is recorded against all the insects logged in London (5 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.
