Amara aenea
In 3 days ~10% in a week ~20%
Amara aenea is a ground beetle common in almost the whole of Europe and Northern Asia. Its range covers also parts of Northern Africa. It is known as the common sun beetle. A. aenea adults are predators that eat other insects, such as the apple maggot and soybean aphid, which are considered pests by the agriculture industry. As such, this beetle is under study for use in integrated pest management. Larvae are omnivorous.
The adults feed on the developing seed of Poa trivialis and smooth meadow grass Poa pratensis. Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Sun Beetle sighting in London on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 705th 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.
April and May
In those months about 10% of wildlife watchers report a Common Sun Beetle in London on a given day, against under 5% in June to March, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Sun Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 13 cities where we can rate Common Sun Beetle sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Munich (Germany, under 5%).
Same family: Carabidae
The closest relatives of the Common Sun Beetle that you can see in London (family Carabidae, Ground Beetles) are Black Clock (about 10%) and Paradromius linearis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Sun Beetle is recorded against all the insects logged in London (23 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.
