With luck
About 10% of wildlife watchers report a Heart Longhorn Beetle sighting in Rome on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 154th most-seen of the 289 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Heart Longhorn Beetle in Rome on a given day, against under 5% in July to April, the lowest months. That is one of Rome's driest months, with about 35 mm of rain against 110 mm in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Heart Longhorn Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 6 cities where we can rate Heart Longhorn Beetle sightings, Rome ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Milan (Italy, about 10%) and Lyon (France, about 10%).
Same family: Cerambycidae
The closest relatives of the Heart Longhorn Beetle that you can see in Rome (family Cerambycidae, Longhorn Beetles) are Herophila tristis (about 10%), Cerambyx welensii (about 10%) and Stenopterus ater (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Heart Longhorn Beetle is recorded against all the insects logged in Rome (10 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.
