Rhynocoris iracundus is an assassin bug belonging to the family Reduviidae, subfamily Harpactorinae. The species was first described by Nikolaus Poda von Neuhaus in 1761. Rhynocoris iracundus differs in colour from R. erythropus in that the sides of the abdomen in R. erythropus are yellow/orange and black, instead of the red and black seen in R. iracundus. In general, the front lobe of the pronotum of R. iracundus is broadly blackened, while in R. rubricus it is red. Furthermore, R. iracundus has narrower red stripes on its legs and abdomen. The base of scutellum is twice as long as the height.

Rare
Under 5% of wildlife watchers report a Rhynocoris iracundus sighting in Vienna on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 378th most-seen of the 1406 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.
May to July
In those months about 10% of wildlife watchers report a Rhynocoris iracundus in Vienna on a given day, against under 5% in August to April, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Rhynocoris iracundus sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Rhynocoris iracundus sightings, Vienna ranks 3rd at under 5%. The best odds are in Budapest (Hungary, about 10%) and Prague (Czechia, about 10%).
GBIF citizen-science records
It is estimated from how often the Rhynocoris iracundus is recorded against all the insects logged in Vienna (40 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.
