Rare
Under 5% of wildlife watchers report a Cruciferous Bug sighting in Madrid on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 350th 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.
June and July
In those months about 10% of wildlife watchers report a Cruciferous Bug in Madrid on a given day, against under 5% in August to May, the lowest months. Those are among Madrid's driest months, with about 15 mm of rain a month against 65 mm in October.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Cruciferous Bug sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 16
Of the 16 cities where we can rate Cruciferous Bug sightings, Madrid ranks 16th at under 5%. The best odds are in Astana (Kazakhstan, about 20%), Vienna (Austria, about 10%) and Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Cruciferous Bug is recorded against all the insects logged in Madrid (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.
