Eurygaster testudinaria is a Palearctic shieldbug. It occurs in Europe from the Northern Mediterranean to southern Scandinavia, and East through Central Asia to northern China and Japan. This species is very difficult to differentiate from Eurygaster maura but testudinaria has a slight central depression at the front of the head. Its colour similarly varies.
Eurygaster testudinaria feeds on Poaceae (grasses). Wikipedia →

With luck
About 10% of wildlife watchers report a Tortoise Bug sighting in Pyrénées National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 350th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

Across all the parks we cover, that three-hour window holds the most Tortoise Bug sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 parks where we can rate Tortoise Bug sightings, Pyrénées National Park ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Bavarian Forest National Park (Germany, about 10%), Vanoise National Park (France, about 10%) and Aigüestortes National Park (Spain, about 10%).
GBIF citizen-science records
It is estimated from how often the Tortoise Bug is recorded against all the insects logged in Pyrénées National Park (30 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.
