Rare
Under 5% of wildlife watchers report a Black Longicorn Beetle sighting in Stockholm on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 202 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.
July and August
In those months about 10% of wildlife watchers report a Black Longicorn Beetle in Stockholm on a given day, against under 5% in September to June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black Longicorn Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 10 cities where we can rate Black Longicorn Beetle sightings, Stockholm has the highest daily chance: under 5%. Next come Prague (Czechia, under 5%) and Berlin (Germany, under 5%).
Same family: Cerambycidae

GBIF citizen-science records
It is estimated from how often the Black Longicorn Beetle is recorded against all the insects logged in Stockholm (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.
