Possible
About 20% of wildlife watchers report a European Rhinoceros Beetle sighting in Budapest on a given day, based on 74 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 404 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June
In that month about 40% of wildlife watchers report a European Rhinoceros Beetle in Budapest on a given day, against under 5% in September to April, the lowest months. That is one of Budapest's wettest months, with about 75 mm of rain against 40 mm in January.
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.
6th of 36
Of the 36 cities where we can rate European Rhinoceros Beetle sightings, Budapest ranks 6th at about 20%. The best odds are in Naples (Italy, about 30%), Yerevan (Armenia, about 30%) and Rome (Italy, about 30%).
Same family: Scarabaeidae
The closest relatives of the European Rhinoceros Beetle that you can see in Budapest (family Scarabaeidae, Scarabs) are Pentodon idiota (about 20%), Mediterranean Spotted Chafer (about 20%) and Apple Blossom Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Rhinoceros Beetle is recorded against all the insects logged in Budapest (74 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.
