Rare
Under 5% of wildlife watchers report a Black Burrowing Bug sighting in Prague on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 470th 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.
July
In that month about 10% of wildlife watchers report a Black Burrowing Bug in Prague on a given day, against under 5% in August to June, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Black Burrowing Bug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 17
Of the 17 cities where we can rate Black Burrowing Bug sightings, Prague ranks 15th at under 5%. The best odds are in Barcelona (Spain, about 10%), Valencia (Spain, about 10%) and Izmir (Turkey, about 10%).
GBIF citizen-science records
It is estimated from how often the Black Burrowing Bug is recorded against all the insects logged in Prague (9 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.
