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 London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1300th most-seen of the 1504 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Variable Longhorn Beetle in London on a given day, so our monthly data shows no clear season.
4th of 4
Of the 4 cities where we can rate Variable Longhorn Beetle sightings, London ranks 4th at under 5%. The best odds are in Vienna (Austria, about 10%), 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 London (family Cerambycidae, Longhorn Beetles) are Spotted Longhorn Beetle (about 10%), Common Grammoptera (about 10%) and Fairy-Ring 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 London (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.
