Graphosoma semipunctatum
In 3 days ~10% in a week ~30%
Graphosoma semipunctatum is a species of true bug living exclusively in the Mediterranean region. The form living on the island of Crete has sometimes been given the name G. creticum. It is very close to Graphosoma italicum. It can be distinguished from G. italicum by black dots along the pronotum instead of lines, and the mostly orange legs.
They are found abundantly on plants in the family Apiaceae. Its red color serves to warn its predators that it is not palatable. Wikipedia →

Rare
Under 5% of wildlife watchers report a Semipunctated Shield Bug sighting in Barcelona on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 263rd most-seen of the 381 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.
July–August and October
In those months about 10% of wildlife watchers report a Semipunctated Shield Bug in Barcelona on a given day, against under 5% in September and November–June, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Semipunctated Shield Bug sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 6
Of the 6 cities where we can rate Semipunctated Shield Bug sightings, Barcelona ranks 5th at under 5%. The best odds are in Jerusalem (Israel, about 20%), Valencia (Spain, about 10%) and Istanbul (Turkey, about 10%).
GBIF citizen-science records
It is estimated from how often the Semipunctated Shield Bug is recorded against all the insects logged in Barcelona (16 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.
