Philonthus cognatus is a rove beetle. Adults are 8 to 10 mm long. They are mainly black in colour, although the elytra have a metallic sheen, and are profusely pitted. A distinctive feature of this species is that the underside of the first antennal segment is yellow, contrasting with the black upperside. It is a common species in Britain. It is also found in Belarus. Wikipedia →

Rare
Under 5% of wildlife watchers report a Philonthus cognatus sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1300th 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.
February
In that month about 10% of wildlife watchers report a Philonthus cognatus in London on a given day, against under 5% in March to January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Philonthus cognatus sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Philonthus cognatus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Philonthus cognatus is recorded against all the insects logged in London (6 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.
