Cicada orni
In 3 days ~50% in a week ~80%
Cicada orni, colloquially called the common cicada or ash cicada, is the type species of cicada belonging to the family Cicadidae, subfamily Cicadinae, and the genus Cicada. The genus name comes directly from the Latin cicada 'buzzer', while the species name orni possibly comes from Fraxinus ornus (Manna Ash or South European Flowering Ash), where this cicada often lay its eggs deep in branches.

Possible
About 20% of wildlife watchers report an Ash Cicada sighting in Rome on a given day, based on 127 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 289 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.
July
In that month about 60% of wildlife watchers report an Ash Cicada in Rome on a given day, against under 5% in November to May, the lowest months. That is one of Rome's driest months, with about 25 mm of rain against 110 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Ash Cicada sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
2nd of 10
Of the 10 cities where we can rate Ash Cicada sightings, Rome ranks 2nd at about 20%. The best odds are in Athens (Greece, about 50%).
Same order: Hemiptera
The closest relatives of the Ash Cicada that you can see in Rome (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 30%), European Striped Shield Bug (about 20%) and Mediterranean Red Bug (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ash Cicada is recorded against all the insects logged in Rome (127 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.
