Tritomegas bicolor, the pied shield bug, is a species of burrowing bug found in Europe. The adult is black and white and 5.5–7 mm (0.22–0.28 in) long. It is found across North Africa, Europe and Central Asia, although in the British Isles, it becomes rarer towards the north, and is absent from Scotland and Ireland. T. bicolor lives mainly on the ground, but is also visible on its host plants — chiefly Lamium (dead nettles) and Ballota nigra (black horehound). Wikipedia →

Rare
Under 5% of wildlife watchers report a Pied Shield Bug sighting in Wadden Sea National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 630th most-seen of the 818 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.

Across all the parks we cover, that three-hour window holds the most Pied Shield Bug sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 parks where we can rate Pied Shield Bug sightings, Wadden Sea National Park ranks 4th at under 5%. The best odds are in Kiskunság National Park (Hungary, about 20%), Cévennes National Park (France, under 5%) and Sierra de Guadarrama National Park (Spain, under 5%).
Same order: Hemiptera

GBIF citizen-science records
It is estimated from how often the Pied Shield Bug is recorded against all the insects logged in Wadden Sea 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.
