Eurygaster integriceps
In 3 days ~10% in a week ~30%
Eurygaster integriceps is a species of shield bug in the family Scutelleridae, commonly known as the sunn pest or corn bug. It is native to much of northern Africa, the Balkans and western and central Asia. It is a major pest of cereal crops especially wheat, barley and oats.
The colour of the sunn pest varies but it is usually light brown. The body is a broad oval about 12 millimetres (0.5 in) long. The scutellum is wide and chitinous and covers the wings and the whole abdomen. The insect lives for about a month during which time the females lay twenty eight to forty two eggs. These are laid in batches each having two neat rows of seven eggs, on the underside of leaves and on the stems of the host plant, or sometimes on weeds. The eggs take six to twenty eight days to hatch and the nymphs moult five times while they feed on the leaves, stems and ears of cereal crops for the next twenty to forty five days. They grow fastest at an air temperature of 20–24 °C (68–75 °F). The second and third instars have a pale abdomen and dark head and thorax. The fourth instar has the rudiments of fore wings and the fifth instar, the rudiments of hind wings as well.

With luck
About 10% of wildlife watchers report a Eurygaster integriceps sighting in Bucharest on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 218th most-seen of the 361 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–April, July and October
In those months about 10% of wildlife watchers report a Eurygaster integriceps in Bucharest on a given day, against under 5% in May–June, August–September and November–February, the lowest months.
Among the best
Of the 3 cities where we can rate Eurygaster integriceps sightings, Bucharest ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Jerusalem (Israel, about 10%) and Tel Aviv (Israel, about 10%).
GBIF citizen-science records
It is estimated from how often the Eurygaster integriceps is recorded against all the insects logged in Bucharest (7 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.
