Rare
Under 5% of wildlife watchers report a Black Longicorn Beetle sighting in Prague on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 281st 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 30%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Black Longicorn Beetle in Prague on a given day, against under 5% in August to May, the lowest months. Those are among Prague's wettest months, with about 80 mm of rain a month against 30 mm in February.
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.
Among the best
Of the 10 cities where we can rate Black Longicorn Beetle sightings, Prague ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Stockholm (Sweden, under 5%).
Same family: Cerambycidae
The closest relatives of the Black Longicorn 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 Black Longicorn Beetle is recorded against all the insects logged in Prague (20 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.
