Rare
Under 5% of wildlife watchers report a White-Shouldered Shieldbug sighting in Pyrénées National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1026th most-seen of the 1277 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.
May
In that month about 10% of wildlife watchers report a White-Shouldered Shieldbug in Pyrénées National Park on a given day, against under 5% in June to April, the lowest months.

GBIF citizen-science records
It is estimated from how often the White-Shouldered Shieldbug is recorded against all the insects logged in Pyrénées National Park (6 verified sightings from 2019 to 2026), 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.
