In 3 days ~20% in a week ~30%
Stenocorus meridianus is a species of longhorn beetle in the Lepturinae subfamily that can be found anywhere in Europe (except for Faroe Islands, Iceland and Ireland, Malta, and parts of Italy such as San Marino, Sardinia, Sicily, and Vatican City), Caucasus, and Kazakhstan. They are 15–27 millimetres (0.59–1.06 in). The species have brown coloured legs, but can have either black (female) or brown (male) coloured prothorax. They occasionally feed on deciduous trees such as elm, maple, and oak. The species life cycle is from 2–3 years, with a flight time from May–July. Wikipedia →

With luck
About 10% of wildlife watchers report a Variable Longhorn Beetle sighting in Vienna on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 276th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Variable Longhorn Beetle in Vienna on a given day, against under 5% in July 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.
Yes
Of the 4 cities where we can rate Variable Longhorn Beetle sightings, Vienna has the highest daily chance: about 10%. Next come Munich (Germany, under 5%) and Prague (Czechia, under 5%).
Same family: Cerambycidae
The closest relatives of the Variable Longhorn Beetle that you can see in Vienna (family Cerambycidae, Longhorn Beetles) are Alpine Longhorn Rosalia (about 10%), Common Grammoptera (about 10%) and Dorcadion aethiops (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Variable Longhorn Beetle is recorded against all the insects logged in Vienna (58 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.
