About the Pied Shield Bug

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 →

GBIF citizen-science records

It is estimated from how often the Pied Shield Bug is recorded against all the insects logged in London (20 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.
