With luck
About 10% of wildlife watchers report a White-Shouldered Shieldbug sighting in Rome on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 214th most-seen of the 289 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March to June
In those months about 10% of wildlife watchers report a White-Shouldered Shieldbug in Rome on a given day, against under 5% in July to February, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most White-Shouldered Shieldbug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 12 cities where we can rate White-Shouldered Shieldbug sightings, Rome ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Bucharest (Romania, about 10%) and Valencia (Spain, about 10%).

GBIF citizen-science records
It is estimated from how often the White-Shouldered Shieldbug is recorded against all the insects logged in Rome (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.
