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 Copenhagen on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 340th most-seen of the 476 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, June and October
In those months about 10% of wildlife watchers report a Common Sun Beetle in Copenhagen on a given day, against under 5% in May, July–September and November–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, Copenhagen ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Munich (Germany, under 5%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Sun Beetle is recorded against all the insects logged in Copenhagen (7 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.
