Chinavia hilaris

The green stink bug or green soldier bug (Chinavia hilaris) is a stink bug of the family Pentatomidae. The species was previously placed in the genus Acrosternum but has been classified in the genus Chinavia in the more recent literature (e.g., Schwertner and Grazia, 2006). However, the Entomological Society of America has not officially recognized this change despite this shift in scientific naming.
The green stink bug's color is typically bright green, with narrow yellow, orange, or reddish edges. It is a large, shield-shaped bug with an elongate, oval form and a length between 13 and 18 mm. It can be differentiated from the species Nezara viridula by its black outermost three antennal segments. Its anterolateral (= in front and away from the middle) pronotal margin is rather straight and not strongly arced, such as in Chinavia pensylvanica.
Both adults and nymphs have large stink glands on the underside of the thorax, extending more than halfway to the edge of the metapleuron. They discharge large amounts of this foul-smelling liquid when disturbed. This liquid, dried and pulverized, was once used at an industrial level to reinforce the smell... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Green Stink Bug is recorded against all the insects logged in Philadelphia (82 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.
