Rare
Under 5% of wildlife watchers report a Rhombic Leatherbug sighting in Madrid on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 328th most-seen of the 457 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 and December
In those months about 10% of wildlife watchers report a Rhombic Leatherbug in Madrid on a given day, against under 5% in January–June and August–November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Rhombic Leatherbug sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 11
Of the 11 cities where we can rate Rhombic Leatherbug sightings, Madrid ranks 8th at under 5%. The best odds are in Bucharest (Romania, about 10%), Berlin (Germany, about 10%) and Prague (Czechia, about 10%).
GBIF citizen-science records
It is estimated from how often the Rhombic Leatherbug is recorded against all the insects logged in Madrid (8 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.
