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 Berlin on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 949th most-seen of the 1065 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
In that month about 10% of wildlife watchers report a Common Sun Beetle in Berlin on a given day, against under 5% in May to March, the lowest months. That is one of Berlin's driest months, with about 30 mm of rain against 80 mm in July.
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, Berlin ranks 7th at under 5%, level with the leaders once rounded. The best odds are in Munich (Germany, under 5%), London (United Kingdom, under 5%) and Copenhagen (Denmark, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Sun Beetle is recorded against all the insects logged in Berlin (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.
