Possible
About 20% of wildlife watchers report a Leather Beetle sighting in Istanbul on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 266 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
October and November
In those months about 30% of wildlife watchers report a Leather Beetle in Istanbul on a given day, against about 10% in March–April, July–August and December–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Leather Beetle sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 18 cities where we can rate Leather Beetle sightings, Istanbul ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Izmir (Turkey, about 20%).
GBIF citizen-science records
It is estimated from how often the Leather Beetle is recorded against all the insects logged in Istanbul (70 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.
