Thyreocoris scarabaeoides
In 3 days ~10% in a week ~20%
Thyreocoris scarabaeoides is a species of shield bug found in Europe. It is small (3–4 mm.), nearly round and dark bronzy coloured. The surface is shining, glabrous and strongly punctured. The antennae are piceous, the scutellum not quite covering the corium and membrane. The legs are black with spinose tibiae and piceous
tarsi. The nymphs and adults feed primarily on violets (Viola), but they are found on the ground under different plant species. Initially, the nymphs live in aggregations. Overwintering is under dry leaf and needle litter, under stones or in moss. Mating takes place from April, the egg laying mainly in May and June. The adult animals of the new generation can be found from late July or August. There is a single generation per year. Wikipedia →

Rare
Under 5% of wildlife watchers report a Scarab Shieldbug sighting in Berlin on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 801st 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 and May
In those months about 10% of wildlife watchers report a Scarab Shieldbug in Berlin on a given day, against under 5% in June to March, the lowest months.
Among the best
Of the 3 cities where we can rate Scarab Shieldbug sightings, Berlin ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Bucharest (Romania, under 5%) and Vienna (Austria, under 5%).
Same order: Hemiptera
The closest relatives of the Scarab Shieldbug that you can see in Berlin (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 40%), Brown Marmorated Stink Bug (about 30%) and Green Shield Bug (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scarab Shieldbug is recorded against all the insects logged in Berlin (8 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.
