With luck
About 10% of wildlife watchers report a European Rhinoceros Beetle sighting in Lisbon on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 441 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.
June to August
In those months about 10% of wildlife watchers report a European Rhinoceros Beetle in Lisbon on a given day, against under 5% in September to May, the lowest months. Those are among Lisbon's driest months, with about 10 mm of rain a month against 95 mm in November.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most European Rhinoceros Beetle sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
28th of 36
Of the 36 cities where we can rate European Rhinoceros Beetle sightings, Lisbon ranks 28th at about 10%. The best odds are in Naples (Italy, about 30%), Yerevan (Armenia, about 30%) and Rome (Italy, about 30%).
GBIF citizen-science records
It is estimated from how often the European Rhinoceros Beetle is recorded against all the insects logged in Lisbon (30 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.
