The body has a velvet-like hair. Elytra are very narrow. Antennae are about as long as the body and clearly segmented. The head and pronotum are black colored and the abdomen has a black background color horizontally crossed by yellow stripes.

With luck
About 10% of wildlife watchers report a Stenopterus rufus sighting in Bucharest on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 153rd most-seen of the 361 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Stenopterus rufus in Bucharest on a given day, against under 5% in August to April, the lowest months. That is one of Bucharest's wettest months, with about 80 mm of rain against 35 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Stenopterus rufus sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 cities where we can rate Stenopterus rufus sightings, Bucharest ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Barcelona (Spain, about 10%) and Tel Aviv (Israel, about 10%).
Same family: Cerambycidae
The closest relatives of the Stenopterus rufus that you can see in Bucharest (family Cerambycidae, Longhorn Beetles) are Dorcadion murrayi (about 10%), Grain Support Beetle (about 10%) and Echinocerus floralis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Stenopterus rufus is recorded against all the insects logged in Bucharest (14 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.
