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 →

With luck
About 10% of wildlife watchers report a Mediterranean Red Bug sighting in Doñana National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 87 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May and October
In those months about 20% of wildlife watchers report a Mediterranean Red Bug in Doñana National Park on a given day, against under 5% in April, June–September and November–January, the lowest months. Those are among Doñana National Park's wettest months, with about 60 mm of rain a month against almost none in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Mediterranean Red Bug sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3

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