In 3 days ~10% in a week ~20%
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 →

Rare
Under 5% of wildlife watchers report a Variable Longhorn Beetle sighting in Prague on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 594th most-seen of the 724 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Variable Longhorn Beetle in Prague on a given day, against under 5% in July to May, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.
3rd of 4
Of the 4 cities where we can rate Variable Longhorn Beetle sightings, Prague ranks 3rd at under 5%. The best odds are in Vienna (Austria, about 10%) and Munich (Germany, under 5%).
Same family: Cerambycidae
The closest relatives of the Variable Longhorn Beetle that you can see in Prague (family Cerambycidae, Longhorn Beetles) are Fairy-Ring Longhorn Beetle (about 10%), The Tanner (about 10%) and Spotted Longhorn Beetle (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 Prague (6 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.
