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 →

Rare
Under 5% of wildlife watchers report a Tortoise Bug sighting in Cévennes National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 896th most-seen of the 996 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.
June and July
In those months about 10% of wildlife watchers report a Tortoise Bug in Cévennes National Park on a given day, against under 5% in August to May, the lowest months. Those are among Cévennes National Park's driest months, with about 60 mm of rain a month against 260 mm in October.
Between 11 am and 2 pm
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.
6th of 6
Of the 6 parks where we can rate Tortoise Bug sightings, Cévennes National Park ranks 6th at under 5%. 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 Cévennes National Park (5 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.
