Rare
Under 5% of wildlife watchers report a Black Burrowing Bug sighting in Istanbul on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 215th most-seen of the 266 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.
April–May and July–August
In those months about 10% of wildlife watchers report a Black Burrowing Bug in Istanbul on a given day, against under 5% in June and September–March, the lowest months.
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.
11th of 17
Of the 17 cities where we can rate Black Burrowing Bug sightings, Istanbul ranks 11th at under 5%. The best odds are in Barcelona (Spain, about 10%), Valencia (Spain, about 10%) and Izmir (Turkey, about 10%).
Same order: Hemiptera

GBIF citizen-science records
It is estimated from how often the Black Burrowing Bug is recorded against all the insects logged in Istanbul (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.
