Piezodorus lituratus, the gorse shield bug, is a species of Pentatomidae, a family of shield bugs. These shield bugs live in many habitats where host plants are present. They prefer dry and warm habitats, especially with sandy soil. Piezodorus lituratus can reach a length of 10–13 mm (0.39–0.51 in). These large shieldbugs occur in two adult colour forms. In the spring when they emerge and mate they are predominantly green, while the new generation that appears in the late summer has purplish-red markings on the pronotum and corium. In autumn they have a much paler color, prior to hibernation they may become darker, but after hibernation they are bright green.
In Piezodorus lituratus var. alliaceus the corium shows a uniform yellow-greenish color. This species could be confused with the green shieldbug, Palomena prasina, but Piezodorus lituratus has a different habitat and red antennae.

With luck
About 10% of wildlife watchers report a Gorse Shield Bug sighting in London on a given day, based on 83 verified sightings from GBIF citizen-science data. It is the 342nd most-seen of the 1504 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.
March–May and September–November
In those months about 10% of wildlife watchers report a Gorse Shield Bug in London on a given day, against under 5% in June–August and December–February, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Gorse Shield Bug sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 19 cities where we can rate Gorse Shield Bug sightings, London ranks 6th at about 10%, level with the leaders once rounded. The best odds are in Kharkiv (Ukraine, about 10%), Birmingham (United Kingdom, about 10%) and Lyon (France, about 10%).
Same family: Pentatomidae
The closest relatives of the Gorse Shield Bug that you can see in London (family Pentatomidae, Stink Bugs) are Green Shield Bug (about 30%), Forest Bug (about 20%) and Southern Green Stink Bug (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gorse Shield Bug is recorded against all the insects logged in London (83 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.
