Scantius aegyptius, the Mediterranean red bug, is a species of red bug in the family Pyrrhocoridae, that is a pest of plant species in the family Malvaceae. These ground-dwelling bugs feed on seeds and seed pods. They are known for their black and red coloration that employs aposematism to deter predators. Their head, antennae and legs are black, and their red back has two round black spots. Nymphs may be completely red, and develop increasing dark spots as they moult. Adults typically measure 7–9 mm in length.
Considered an invasive species in North America, it was first recorded in California in 2009. As of 2018, it could be found in most Southern California counties, as well as some in Central California. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Mediterranean Red Bug is recorded against all the insects logged in Sierra Nevada 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.
